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,

Hi, Mark,
>From your post I could not figure out, what is your question. May be you should formulate it clearer, so that we see, if somebody might help. There is a second problem: the code above does not look like Mathematica syntax, and I really cannot understand, what it means. I propose that you rewrite it in a legal Mathematica way, and, if after that it still does not work, send it once more.
Have fun, Alexei
