Fourier Transform of a productof Green functions

  1. Jan 26, 2010 #1
    Guys, how do u get the fourier transform of a product of Greens Functions?I have to get fourier transform of:

    G[tex]_{el}[/tex](k+q,[tex]\tau[/tex]-[tex]\tau1[/tex])*G[tex]_{el}[/tex](k,[tex]\tau1[/tex]) where [tex]\tau[/tex] and [tex]\tau1[/tex] are two different times ([tex]\tau[/tex]>[tex]\tau1[/tex]) and q is phonon momentum and k is electron momentum....


    Thanks
