The traditional approach to the numerical solution of hyperbolic partial differential equations is relies on finite difference and finite volume methods of low order order of accuracy. The aim of this talk is to explore an alternative route based on the use of hp-finite element methods. This class of techniques admits both mesh adaptation and adaptive alteration of the degree of the approximating piecewise polynomial to improve accuracy, if required. We shall develop the error analysis of the hp-version of the discontinuous Galerkin finite element method and illustrate the implementation of the a posteriori error bounds into an adaptive algorithm capable of delivering numerical approximations to the quantity of interest automatically, to within a user-prescribed tolerance. The talk is based on joint work with Christoph Schwab (ETH Zurich) and Paul Houston (Leicester).
