Optimal a priori error estimates in weighted Sobolev spaces for the Poisson problem with singular sources
(EDP Sciences, 2021-08)
We study the problem -Δu=f, where f has a point-singularity. In particular, we are interested in f = δx0, a Dirac delta with support in x0, but singularities of the form f|x - x0|-s are also considered. We prove the stability ...
