WebThe miracle of Green's method is that once G(r, r ′) is known, the solution to Poisson's equation for any f can be obtained at the mere cost of evaluating a three-dimensional integral. And since Green's equation is the same as Laplace's equation except at r = r ′, the task of solving it should be relatively straightforward.
