Hi, Mathematica hangs up when trying to compute the Fourier transform of F[X_, Y_] := E^(-100 + 20*X - 2*X^2 - 10*Y - Y^2/2) + E^(-100 - 2*X^2 - 10*Y - Y^2/2 + 10*(10 + Y)) + E^(-200 + 20*X - 2*X^2 - 10*Y - Y^2/2 + 10*(2*X + Y)) + E^(-200 - 2*X^2 - 10*Y - Y^2/2 + 10*(10 + Y) + 10*(2*X + Y)) FourierTransform[F[X,Y],Y,P] (keeps running forever) However, it computes very fast the Fourier transform of each term separately. I am using Mathematica 4.1 in Windows 2000. Mathematica 2.2 computed correctly this fourier transform. Any idea? Daniel Arteaga
