The mortar finite volume method with the Crouzeix--Raviart element for elliptic problems
A mortar finite volume method for the discretization of selfadjoint elliptic boundary value problems is presented. It is based on the mortar Crouzeix-Raviart non-conforming finite element spaces. Optimal \(H^1\) and \(L^2\) error estimates are proved.
