We present a class of Schwarz preconditioners for discontinuous Galerkin approximations of elliptic problems. We provide a unified framework for the construction and analysis of two-level methods which share the features of the classical Schwarz techniques for conforming finite element discretizations. Numerical experiments confirming the theoretical results are also included.
