  Full Text
In this paper we analyse the problem of computing eigenvalues and eigenfunotions of the Laplace operator and of the grad-div operator by discontinuous Galerkin (DG) methods. Conditions under which DG methods provide spectrally correct approximations are given in both cases.

Keywords:  Discontinuous Galerkin methods; Eigenvalue problems
