In this paper, the discontinuous Galerkin method for the positive and symmetric, linear hyperbolic systems is constructed and analyzed by using bilinear finite elements on a rectangular domain, and an O(h 2 )-order superconvergence error estimate is established under the conditions of almost uniform
