Consider:
##\nabla^{2} V(\vec{r})= \delta(\vec{r})##
By taking the Fourier transform, the differential equation dissapears. Then by transforming that expression back I find something like ##V(r) \sim \frac{1}{r}##.
I seem to have lost the homogeneous solutions in this process. Where does this happen?
