Subject: computation of two-point objects


hello,
I have been stuck for decades trying to calculate the world function for

ds^2=-(1+2\sigma)dv^2+2dvdr+r(r-2\sigma v)(d\theta^2+\sin(\theta)^2d\phi^2)
\phi=\n(1-2\sigma v/r)/2
R_{ab}=2\phi_a\phi_b

one gets elliptic functions if one try direct method, The trouble with
approximations is that it is hard to tell if they converge.....

bye,

/\/\,
