ارجوو منكم المساعدة في حل هذه المسائل ياليت يكون بالتفصيل
. This problem concerns the Green’s function for the diffusion equation in an arbitrary number of spatial
dimensions d.
(a) Use an eigenfunction expansion to show that the Green’s function is
![]()
where (t) is the Heaviside step function.
(b) Find the Green’s function by taking a Fourier transform of the diusion equation with respect to
the spatial variables. You should, of course, get the same answer.
