Estimation of penalty parameters for symmetric interior penalty Galerkin methods. (English)
[J] J. Comput. Appl. Math. 206, No. 2, 843-872 (2007). ISSN 0377-0427

The numerical approximation of a linear elliptic problem by the discontinuous Galerkin method is considered. Computable lower bounds for the penalty parameters are presented.
