comment Integro-differential equation
Dear acl, As much as I tried so far I couldn't find an algorithm to take care of the 2nd derivative under the integral sign. So yes, I need an algorithm or even a clue to start.

comment discrete Fourier transform
Guys,I do get the same result on my machine,but I think this Fourier analysis doesn't make sense,at least my supervisor says so.he says I have to tell the program that my function is periodic,so that the Fourier transform of it should go to zero for t infinity.

comment Integro-differential equation
@Leoinid:I tried to remove the 2nd derivative under the integral,but because the kernel is a 2nd type modified Bessel function it would lead to a divergent 2nd derivative of kernel which make it worse,so I think that I have to deal with this equation the way it is and solve it by discretization if possible.any idea how to discretize?

comment Integro-differential equation
Guys,first of all I should say that K(x,u) is first modified Bessel function and u is just a variable under the Integral.secondly I haven't tried your answers so far but I think Leonid's is understandable.@ Leonid:Does any solver exist in mathematica for this?

comment integro differential equation
Guys,my integral limits are from -infinity to infinity and yes the D is partial derivative.y is a function of x,t.
