Title: How Large is $A_g(\mathbb{F}_q)$? Authors: Michael Lipnowski, Jacob Tsimerman Categories: math.NT Comments: 38 pages \\ Let $B(g,p)$ denote the number of isomorphism classes of $g$dimensional abelian varieties over the finite field of size $p.$ Let $A(g,p)$ denote the number of isomorphism classes of principally polarized $g$ dimensional abelian varieties over the finite field of size $p.$ We derive upper bounds for $B(g,p)$ and lower bounds for $A(g,p)$ for $p$ fixed and $g$ increasing. The extremely large gap between the lower bound for $A(g,p)$ and the upper bound $B(g,p)$ implies some statistically counterintuitive behavior for abelian varieties of large dimension over a fixed finite field. \\ ( http://arxiv.org/abs/1511.02212 , 35kb)  \\ arXiv:1511.02221 Date: Fri, 6 Nov 2015 20:36:36 GMT (11kb)
Title: On correlations of certain multiplicative functions Authors: R. Balasubramanian, Sumit Giri, Priyamvad Srivastav Categories: math.NT MSCclass: 11N \\ In this paper, the correlation function of the form $\frac{1}{x}\sum_{n \leq x} F(n) G(nh)$, were $F=f*1$ and $G=g*1$ with $f$ and $g$ small on an average, has been considered. We obtain an estimation formulae for this mean value depending on different order of magnitude of $f$ and $g$. We compute an average of shifted Euler totient function $\varphi(nh)$ over squarefree integers $n$ and in general expressions of the type $\sum_{n \leq x} \mu^2(n) G(nh)$, where $G$ is close to $1$ on primes. For certain cases where $f$ and $g$ are small, we make some improvements in the error terms of the corresponding estimations. \\ ( http://arxiv.org/abs/1511.02221 , 11kb)  \\ arXiv:1511.01930 Date: Thu, 5 Nov 2015 21:53:34 GMT (210kb)

Math MSCclass: 46L08, 47A30, 46L05, 47B47 \\ Utilizing the BirkhoffJames orthogonality, we present some characterizations of the normparallelism for elements of $\mathbb{B}(\mathscr{H})$ defined on a finite dimensional Hilbert space, elements of a Hilbert $C^*$module over the $C^*$algebra of compact operators and elements of an arbitrary $C^*$algebra. We also consider the characterization of norm parallelism problem for operators on a finite dimensional Hilbert space when the operator norm is replaced by the Schatten $p$norm.

Title: A Multistage Stochastic Programming Approach for Network Capacity Expansion with Multiple Sources of Capacity Authors: Majid Taghavi, Kai Huang Categories: math.OC \\ In networks, there are often more than one source of capacity. The capacities can be permanently or temporarily owned by the decision maker. Depending on the nature of sources, we identify the permanent capacity, spot market capacity and contract capacity. We use a scenario tree to model the uncertainty, and build a multistage stochastic integer program that can incorporate multiple sources and multiple types of capacities in a general network. We propose two solution methodologies for the problem. Firstly, we design an asymptotically convergent approximation algorithm. Secondly, we design a cutting plane algorithm based on Benders decomposition to find tight bounds for the problem. The numerical experiments show superb performance of the proposed algorithms compared with commercial software. \\ ( http://arxiv.org/abs/1511.01922 , 65kb)  \\ arXiv:1511.01935 Date: Thu, 5 Nov 2015 22:24:39 GMT (7217kb,D)
Title: A Multiresolution Ensemble Kalman Filter using Wavelet Decomposition Authors: Kyle S. Hickmann, Humberto C. Godinez Categories: math.OC physics.dataan \\ We present a method of using classical wavelet based multiresolution analysis to separate scales in model and observations during data assimilation with the ensemble Kalman filter. In many applications, the underlying physics of a phenomena involve the interaction of features at multiple scales. Blending of observational and model error across scales can result in large forecast inaccuracies since large errors at one scale are interpreted as inexact data at all scales. Our method uses a transformation of the observation operator in order to separate the information from different scales of the observations. This naturally induces a transformation of the observation covariance and we put forward several algorithms to efficiently compute the transformed covariance. Another advantage of our multiresolution ensemble Kalman filter is that scales can be weighted independently to adjust each scale's effect on the forecast. To demonstrate feasibility we present applications to a one dimensional KuramotoSivashinsky (KS) model with scale dependent observation noise and an application involving the forecasting of solar photospheric flux. The latter example demonstrates the multiresolution ensemble Kalman filter's ability to account for scale dependent model error. Modeling of photospheric magnetic flux transport is accomplished by the Air Force Data Assimilative Photospheric Transport (ADAPT) model. \\ ( http://arxiv.org/abs/1511.01935 , 7217kb)  \\ arXiv:1511.01965 Date: Fri, 6 Nov 2015 01:07:35 GMT (355kb,D)
Title: Sequential Detection of Market shocks using Riskaverse Agent Based Models Authors: Vikram Krishnamurthy and Sujay Bhatt Categories: math.OC qfin.TR \\ This paper considers a statistical signal processing problem involving agent based models of financial markets which at a microlevel are driven by socially aware and risk averse trading agents. These agents trade (buy or sell) stocks by exploiting information about the decisions of previous agents (social learning) via an order book in addition to a private (noisy) signal they receive on the value of the stock. We are interested in the following: (1) Modelling the dynamics of these risk averse agents, (2) Sequential detection of a market shock based on the behaviour of these agents. Structural results which characterize social learning under a risk measure, CVaR (Conditional Valueatrisk), are presented and formulation of the Bayesian change point detection problem is provided. The structural results exhibit two interesting prop erties: (i) Risk averse agents herd more often than risk neutral agents (ii) The stopping set in the sequential detection problem is nonconvex. The framework is validated on data from the Yahoo! Tech Buzz game dataset. \\ ( http://arxiv.org/abs/1511.01965 , 355kb)  \\ arXiv:1511.02089 Date: Fri, 6 Nov 2015 14:24:01 GMT (1683kb,D)
Title: EarthMoon Lyapunov to Lyapunov Mission: Long Time Duration, LowThrust Transfer Authors: Maxime Chupin (LJLL), Thomas Haberkorn (MAPMO), Emmanuel Tr\'elat (LJLL) Categories: math.OC math.DS \\ In this work, we develop a new method to design missions with lowthrust propulsion. In the Circular Restricted Three Body Problem, the knowledge of invariant manifolds helps us to initialize an indirect method solving a transfer mission between periodic Lyapunov orbits. Indeed, using the Pontryagin Maximum Principle, the optimal control problem is solved using Newtonlike algorithms finding the zero of a shooting function. We first compute an admissible trajectory using a heteroclinic orbit between the two periodic orbits. It is then used to initialize a multiple shooting method in order to release the constraint. We finally optimize the terminal points on the periodic orbits. Moreover, we use continuation methods on position and on thrust, in order to gain robustness. \\ ( http://arxiv.org/abs/1511.02089 , 1683kb)  \\ arXiv:1511.02180 Date: Fri, 6 Nov 2015 18:15:40 GMT (10999kb,D)
Title: Stabilization of a Rigid Body Payload with Multiple Cooperative Quadrotors Authors: Farhad A. Goodarzi and Taeyoung Lee Categories: math.OC Comments: arXiv admin note: substantial text overlap with arXiv:1501.04910 \\ This paper presents the full dynamics and control of arbitrary number of quadrotor unmanned aerial vehicles (UAV) transporting a rigid body. The rigid body is connected to the quadrotors via flexible cables where each flexible cable is modeled as a system of arbitrary number of serially connected links. It is shown that a coordinatefree form of equations of motion can be derived for the complete model without any simplicity assumptions that commonly appear in other literature, according to Lagrangian mechanics on a manifold. A geometric nonlinear controller is presented to transport the rigid body to a fixed desired position while aligning all of the links along the vertical direction. A rigorous mathematical stability proof is given and the desirable features of the proposed controller are illustrated by numerical examples and experimental results. \\ ( http://arxiv.org/abs/1511.02180 , 10999kb)  \\ arXiv:1511.02182 Date: Fri, 6 Nov 2015 18:26:30 GMT (380kb,D)
Title: Optimizing Damper Connectors for Adjacent Buildings Authors: K. Bigdeli and W. Hare and J. Nutini and S. Tesfamariam Categories: math.OC \\ Many theoretical and experimental studies have used heuristic methods to investigate the dynamic behaviour of the passive coupling of adjacent structures. However, few papers have used optimization techniques with guaranteed convergence in order to increase the efficiency of the passive coupling of adjacent structures. In this paper, the combined problem of optimal arrangement and mechanical properties of dampers placed between two adjacent buildings is considered. A new bilevel optimization approach is presented. The outerloop of the approach optimizes damper configuration and is solved using the ``inserting dampers'' method, which was recently shown to be a very effective heuristic method. Under the assumption that the dampers have varying damper coefficients, the innerloop finds the optimal damper coefficients by solving an $n$dimensional optimization problem, where derivative information of the objective function is not available. Three different nongradient methods are compared for solving the inner loop: a genetic algorithm (GA), the mesh adaptive direct search (MADS) algorithm, and the robust approximate gradient sampling (RAGS) algorithm. It is shown that by exploiting this new bilevel problem formulation, modern derivative free optimization techniques with guaranteed convergence (such as MADS and RAGS) can be used. The results indicate a great increase in the efficiency of the retrofitting system, as well as the existence of a threshold on the number of dampers inserted with respect to the efficiency of the retrofitting system. \\ ( http://arxiv.org/abs/1511.02182 , 380kb)  \\ arXiv:1511.02190 Date: Fri, 6 Nov 2015 18:46:01 GMT (34kb)

Title: Cooperation and Competition among Energy Storages Authors: Jesus E. ContrerasOca\~na, Miguel A. OrtegaVazquez, Baosen Zhang Categories: math.OC cs.SY \\ We study competition and cooperation among a group of storage units. We show that as the number of storages increases, the profit of storages approaches zero under Nash competition. We propose two ways in which storages can achieve nonzero profit and show that they are optimal in the sense that storages achieve the maximum possible profit. The first is a decentralized approach in which storages are exposed to artificial cost functions that incentivize them to behavior as a coalition. No private information needs to be exchanged between the storages to calculate the artificial function. The second is a centralized approach in which an aggregator coordinates and splits profits with storages in order to achieve maximum profit. We use Nash's axiomatic bargaining problem to model and predict the profit split between aggregator and storages. \\ ( http://arxiv.org/abs/1511.02201 , 383kb)  \\ arXiv:1511.02204 Date: Fri, 6 Nov 2015 19:31:52 GMT (2119kb,D)
Title: An Extended FrankWolfe Method with "InFace" Directions, and its Application to LowRank Matrix Completion Authors: Robert M. Freund and Paul Grigas and Rahul Mazumder Categories: math.OC stat.CO stat.ML Comments: 25 pages, 3 tables and 2 figues MSCclass: 90C25 ACMclass: G.1.6 \\ Motivated principally by the lowrank matrix completion problem, we present an extension of the FrankWolfe method that is designed to induce nearoptimal solutions on lowdimensional faces of the feasible region. This is accomplished by a new approach to generating ``inface" directions at each iteration, as well as through new choice rules for selecting between inface and ``regular" FrankWolfe steps. Our framework for generating inface directions generalizes the notion of awaysteps introduced by Wolfe. In particular, the inface directions always keep the next iterate within the minimal face containing the current iterate. We present computational guarantees for the new method that trade off efficiency in computing nearoptimal solutions with upper bounds on the dimension of minimal faces of iterates. We apply the new method to the matrix completion problem, where lowdimensional faces correspond to lowrank matrices. We present computational results that demonstrate the effectiveness of our methodological approach at producing nearlyoptimal solutions of very low rank. On both artificial and real datasets, we demonstrate significant speedups in computing very lowrank nearlyoptimal solutions as compared to either the FrankWolfe method or its traditional awaystep variant. \\ ( http://arxiv.org/abs/1511.02204 , 2119kb)  \\ arXiv:1511.01975 Date: Fri, 6 Nov 2015 03:09:31 GMT (23kb)
Title: Persistence of centrality in random growing trees Authors: Varun Jog and PoLing Loh Categories: math.PR cs.DM cs.SI math.ST stat.TH Comments: 21 pages MSCclass: 60C05 \\ We investigate properties of node centrality in random growing tree models. We focus on a measure of centrality that computes the maximum subtree size of the tree rooted at each node, with the most central node being the tree centroid. For random trees grown according to a preferential attachment model, a uniform attachment model, or a diffusion processes over a regular tree, we prove that a single node persists as the tree centroid after a finite number of steps, with probability 1. Furthermore, this persistence property generalizes to the top $K \ge 1$ nodes with respect to the same centrality measure. We also establish necessary and sufficient conditions for the size of an initial seed graph required to ensure persistence of a particular node with probability $1\epsilon$, as a function of $\epsilon$: In the case of preferential and uniform attachment models, we derive bounds for the size of an initial hub constructed around the special node. In the case of a diffusion process over a regular tree, we derive bounds for the radius of an initial ball centered around the special node. Our necessary and sufficient conditions match up to constant factors for preferential attachment and diffusion tree models. \\ ( http://arxiv.org/abs/1511.01975 , 23kb)  \\ arXiv:1511.02118 Date: Fri, 6 Nov 2015 15:37:04 GMT (35kb)

The local properties of the infinite volume Gibbs measure, related to whether a macroscopic configuration is realized as a homogeneous state or as a mixture of pure states, are also studied by constructing the corresponding YoungGibbs measures. \\ ( http://arxiv.org/abs/1511.02118 , 35kb)  \\ arXiv:1511.02211 Date: Fri, 6 Nov 2015 19:56:55 GMT (10kb)
Title: A sharp lower bound for choosing the maximum of an independent sequence Authors: Pieter C. Allaart and Jose A. Islas Categories: math.PR Comments: 13 pages MSCclass: 60G40 \\ This paper considers a variation of the fullinformation secretary problem where the random variables to be observed are independent but not necessary identically distributed. The main result is a sharp lower bound for the optimal win probability. Precisely, if $X_1,\dots,X_n$ are independent random variables with known continuous distributions and $V_n(X_1,\dots,X_n):=\sup_\tau P(X_\tau=M_n)$, where $M_n:=\max\{X_1,\dots,X_n\}$ and the supremum is over all stopping times adapted to $X_1,\dots,X_n$, then $$V_n(X_1,\dots,X_n)\geq \left(1\frac{1}{n}\right)^{n1},$$ and this bound is attained. The method of proof consists in reducing the problem to that of a sequence of twovalued random variables, and then applying Bruss' sumtheodds theorem (2000). In order to obtain a sharp bound for each $n$, we improve Bruss' lower bound (2003) for the sumtheodds problem. \\ ( http://arxiv.org/abs/1511.02211 , 10kb)  \\ arXiv:1511.02130 Date: Fri, 6 Nov 2015 15:59:49 GMT (16kb)

This confirms a conjecture by Ehrig and Stroppel concerning the topology of the equalrow Springer fiber for the even orthogonal group. Moreover, we show that every tworow Springer fiber for the symplectic group is homeomorphic (even isomorphic as an algebraic variety) to a connected component of a certain tworow Springer fiber for the even orthogonal group. \\ ( http://arxiv.org/abs/1511.01961 , 36kb)  \\ arXiv:1511.02145 Date: Fri, 6 Nov 2015 16:38:53 GMT (26kb)

Title: False Discoveries Occur Early on the Lasso Path Authors: Weijie Su, Malgorzata Bogdan, Emmanuel Candes Categories: math.ST cs.IT math.IT stat.ML stat.TH \\ In regression settings where explanatory variables have very low correlations and where there are relatively few effects each of large magnitude, it is commonly believed that the Lasso shall be able to find the important variables with few errorsif any. In contrast, this paper shows that this is not the case even when the design variables are stochastically independent. In a regime of linear sparsity, we demonstrate that true features and null features are always interspersed on the Lasso path, and that this phenomenon occurs no matter how strong the effect sizes are. We derive a sharp asymptotic tradeoff between false and true positive rates or, equivalently, between measures of type I and type II errors along the Lasso path. This tradeoff states that if we ever want to achieve a type II error (false negative rate) under a given threshold, then anywhere on the Lasso path the type I error (false positive rate) will need to exceed a given threshold so that we can never have both errors at a low level at the same time. Our analysis uses tools from approximate message passing (AMP) theory as well as novel elements to deal with a possibly adaptive selection of the Lasso regularizing parameter. \\ ( http://arxiv.org/abs/1511.01957 , 225kb)  \\ arXiv:1511.02112 Date: Fri, 6 Nov 2015 15:21:16 GMT (539kb,D)

Title: The $\mathbb{Z}_2^n$ DiracDunkl operator and a higher rank BannaiIto algebra Authors: Hendrik De Bie, Vincent X. Genest and Luc Vinet Categories: mathph math.CA math.MP math.QA Comments: 20 pages \\ The kernel of the $\mathbb{Z}_2^{n}$ DiracDunkl operator is examined. The symmetry algebra $\mathcal{A}_{n}$ of the associated DiracDunkl equation on $\mathbb{S}^{n1}$ is determined and is seen to correspond to a higher rank generalization of the BannaiIto algebra. A basis for the polynomial nullsolutions of the DiracDunkl operator is constructed. The basis elements are joint eigenfunctions of a maximal commutative subalgebra of $\mathcal{A}_{n}$ and are given explicitly in terms of Jacobi polynomials. The symmetry algebra is shown to act irreducibly on this basis via raising/lowering operators. A scalar realization of $\mathcal{A}_{n}$ is proposed. \\ ( http://arxiv.org/abs/1511.02177 , 19kb)

Title: Hamiltonian Path in 2Trees Authors: P.Renjith and N.Sadagopan Categories: cs.DM math.CO Comments: 22 pages, 16 figures \\ For a graph, a spanning path is a path containing all vertices and it is also known as \emph{Hamiltonian path}. For general graphs, there is no known necessary and sufficient condition for the existence of Hamiltonian path and the complexity of finding a Hamiltonian path in general graphs is NPComplete. We present a necessary and sufficient condition for the existence of Hamiltonian path in 2trees. Using our characterization, we also present a polynomialtime algorithm for the existence of Hamiltonian path in 2trees. We also highlight the fact that 2trees are wellknown subclass of chordal and planar graphs. This paper makes the first attempt in identifying a nontrivial subclass of planar graphs where Hamiltonian path is polynomialtime solvable which is otherwise NPComplete on planar as well as chordal graphs. Our characterization is based on a deep understanding of the structure of 2trees and we believe that the combinatorics presented here can be used in other combinatorial problems restricted to 2trees. \\ ( http://arxiv.org/abs/1511.02038 , 131kb)  \\ arXiv:1511.02147 (*crosslisting*) Date: Fri, 6 Nov 2015 16:40:14 GMT (50kb)

They are mainly invoked to explain the various fermion mass hierarchies and forbid dangerous superpotential terms. In string models they are usually associated to the geometry of the compactification manifold and more particularly to the magnetised branes in toroidal compactifications. Motivated by these facts, in this note we propose a unified framework to construct representations of finite discrete family groups based on the automorphisms of the discrete and finite Heisenberg group.

Title: A quantitative performance analysis for Stokes solvers at the extreme scale Authors: Bj\"orn Gmeiner and Markus Huber and Lorenz John and Ulrich R\"ude and Barbara Wohlmuth Categories: cs.CE cs.MS cs.NA math.NA MSCclass: 65N55, 65Y05, 68Q25 \\ This article presents a systematic quantitative performance analysis for large finite element computations on extreme scale computing systems. Three parallel iterative solvers for the Stokes system, discretized by low order tetrahedral elements, are compared with respect to their numerical efficiency and their scalability running on up to $786\,432$ parallel threads. A genuine multigrid method for the saddle point system using an Uzawatype smoother provides the best overall performance with respect to memory consumption and timetosolution. The largest system solved on a Blue Gene/Q system has more than ten trillion ($1.1 \cdot 10 ^{13}$) unknowns and requires about 13 minutes compute time. Despite the matrix free and highly optimized implementation, the memory requirement for the solution vector and the auxiliary vectors is about 200 TByte. Brandt's notion of "textbook multigrid efficiency" is employed to study the algorithmic performance of iterative solvers. A recent extension of this paradigm to "parallel textbook multigrid efficiency" makes it possible to assess also the efficiency of parallel iterative solvers for a given hardware architecture in absolute terms. The efficiency of the method is demonstrated for simulating incompressible fluid flow in a pipe filled with spherical obstacles. \\ ( http://arxiv.org/abs/1511.02134 , 7021kb)  \\ arXiv:1511.02188 (*crosslisting*) Date: Fri, 6 Nov 2015 18:40:52 GMT (139kb,D)
Title: Efficient FunctionalBased Adaptation for CFD Applications Authors: William C. Tyson and Christopher J. Roy Categories: physics.fludyn math.NA physics.compph \\ Adjoint methods have gained popularity in recent years for driving adaptation procedures which aim to reduce error in solution functionals. While adjoint methods have been proven effective for functionalbased adaptation, the practical implementation of an adjoint method can be quite burdensome since code developers constantly need to ensure and maintain a dual consistent discretization as updates are made. Also, since most engineering problems consider multiple functionals, an adjoint solution must be obtained for each functional of interest which can increase the overall computational cost significantly. In this paper, an alternative to adjoints is presented which uses a sparse approximate inverse of the Jacobian of the residual to obtain approximate adjoint sensitivities for functionalbased adaptation indicators. Since the approximate inverse need only be computed once, it can be recycled for any number of functionals making the new approach more efficient than a conventional adjoint method. This new method for functionalbased adaptation will be tested using the quasi1D nozzle problem, and results are presented for functionals of integrated pressure and entropy. \\ ( http://arxiv.org/abs/1511.02188 , 139kb)  \\ arXiv:1511.01942 (*crosslisting*) Date: Thu, 5 Nov 2015 22:45:12 GMT (1037kb,D)
Title: Stop Wasting My Gradients: Practical SVRG Authors: Reza Babanezhad, Mohamed Osama Ahmed, Alim Virani, Mark Schmidt, Jakub Kone\v{c}n\'{y}, Scott Sallinen Categories: cs.LG math.OC stat.CO stat.ML \\ We present and analyze several strategies for improving the performance of stochastic variancereduced gradient (SVRG) methods. We first show that the convergence rate of these methods can be preserved under a decreasing sequence of errors in the control variate, and use this to derive variants of SVRG that use growingbatch strategies to reduce the number of gradient calculations required in the early iterations. We further (i) show how to exploit support vectors to reduce the number of gradient computations in the later iterations, (ii) prove that the commonlyused regularized SVRG iteration is justified and improves the convergence rate, (iii) consider alternate minibatch selection strategies, and (iv) consider the generalization error of the method. \\ ( http://arxiv.org/abs/1511.01942 , 1037kb)  \\ arXiv:1511.02124 (*crosslisting*) Date: Fri, 6 Nov 2015 15:48:53 GMT (1614kb,D)
Title: Barrier FrankWolfe for Marginal Inference Authors: Rahul G. Krishnan, Simon LacosteJulien, David Sontag Categories: stat.ML cs.LG math.OC Comments: 25 pages, 12 figures, To appear in Neural Information Processing Systems (NIPS) 2015 \\ We introduce a globallyconvergent algorithm for optimizing the treereweighted (TRW) variational objective over the marginal polytope. The algorithm is based on the conditional gradient method (FrankWolfe) and moves pseudomarginals within the marginal polytope through repeated maximum a posteriori (MAP) calls. This modular structure enables us to leverage blackbox MAP solvers (both exact and approximate) for variational inference, and obtains more accurate results than treereweighted algorithms that optimize over the local consistency relaxation. Theoretically, we bound the suboptimality for the proposed algorithm despite the TRW objective having unbounded gradients at the boundary of the marginal polytope. Empirically, we demonstrate the increased quality of results found by tightening the relaxation over the marginal polytope as well as the spanning tree polytope on synthetic and realworld instances. \\ ( http://arxiv.org/abs/1511.02124 , 1614kb) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  \\ arXiv:1308.2203 replaced with revised version Fri, 6 Nov 2015 03:45:08 GMT (18kb)
