Abstract
This paper presents an error estimate in the L 2 -norm for the discontinuous Galerkin finite element methods (DGFEM) for elliptic problems with low regularity solutions. The Raviart–Thomas interpolation operator is employed to derive the new result, which complements the mesh-dependent energy norm error estimates in Gudi (2010) [2]. Numerical results corroborate the theoretical analysis.
