A priori error analysis of space–time Trefftz discontinuous Galerkin methods for wave problems [PDF]
, 2015 We present and analyse a space–time discontinuous Galerkin method for wave propagation problems. The special feature of the scheme is that it is a Trefftz method, namely that trial and test functions are solution of the partial differential equation to ...
