The regularity of weak and very weak solutions of the Poisson equation on polygonal domains with mixed boundary conditions (part I)
Adam Kubica · Applicationes Mathematicae · 2004
We examine the regularity of weak and very weak solutions of the Poisson equation on polygonal domains with data in $L^2$. We consider mixed Dirichlet, Neumann and Robin boundary conditions. We also describe the singular part of weak and very weak solutio
