Anisotropic regularity and optimal rates of convergence for the Finite Element Method on three dimensional polyhedral domains
Constantin Bacuta, Anna L. Mazzucato, Victor Nistor
We consider the model Poisson problem , on $\pa Ω$, where is a bounded polyhedral domain in $\RR^n$. The objective of the paper is twofold. The first ob…
