Finding Green's function for diffusion equation

  1. Dec 8, 2014 #1
    1. The problem statement, all variables and given/known data
    Find the solution for:
    [tex]({\partial{}_t}^2 -D \Delta^2)G(\vec{r},t;\vec{r}_o,t_o)=\delta(\vec{r}-\vec{r}_o)\delta(t-t_o)[/tex]
    In two dimensions.
    2. Relevant equations

    3. The attempt at a solution
    Am I supposed to use bessel eqs? I'm kind of stuck in starting the problem :L

    I suggest using Fourier and/or Laplace transforms.
