Date: Dec 15, 2012 12:29 PM Author: Hugo Subject: Ask for help to evaluate an equation I want to evaluate the following equation with mathematica but it seems i'm doing something wrong.

Sum[(-1)^n/A^(n+1)t^(1+n-k(1-eta))beta^(n-k) Binomial[n,k](alpha Gamma[1-eta])^k/Gamma[2+n-k(1-eta)],{n,0,Infinity},{k,0,Infinity}]

Any help would be appreciate it
