We prove stability and derive error estimates for the recently introduced central discontinuous Galerkin method, in the context of linear hyperbolic equations with possibly discontinuous solutions. A comparison between the central discontinuous Galerkin method and the regular discontinuous Galerkin method in this context is also made. Numerical experiments are provided to validate the quantitative conclusions from the analysis.
Mathematics Subject Classification: 65M60
Key words: Central discontinuous Galerkin method / discontinuous Galerkin method / linear hyperbolic equation / stability / error estimate.
