Source abstract

Abstract In this paper, we provide an error estimation of Raviart–Thomas interpolation of degree 0 on anisotropic simplices without imposing any geometric condition on the elements. Although the results are known, we present an alternative proof using a unified approach based on the Babuška–Aziz trick.
