Inverse Laplace transform problem

  1. Aug 25, 2009 #1

    I am trying to solve a PDE for it's Green function, I found myself in a position to know G(is) where "i" is imaginary unit, G(s) is a Laplace transform of g(t) and g(t) is the Green's function I am after. So, I've been snooping around and found Mellin's inverse formula at


    Should I insert variable transform of s = -i*u over there and setting gamma to zero, I find that green's function g(t) is a Fourier transform of G(-iu) divided by a factor. If I can make sure I can set gamma to zero, is this procedure "legal"?

    Any input or suggestion is appriciated!
