Singular behavior of elliptic problems in non Hilbertian Sobolev spaces
An elliptic boundary value problem in nonsmooth domains, which contain corners, edges and vertices, is considered. Using the theory of sums of operators in Banach spaces, the author derives some optimal regularity and singularity results for solutions in the Sobolev spaces built on \(L^p\) with general \(p\).
