Discontinuos Petrov-Galerkin Methods in Banach Spaces
Abstract
Following Muga and van der Zee [8], we generalize the standard Discontinuous Petrov-Galerkin method, based on Hilbert spaces, to Banach spaces. Numerical experiments using model 1D convection- dominated diffusion problem are performed and compared with Hilbert setting. It is shown that Banach-based method gives solutions less susceptible to Gibbs phenomenon. h-adaptiviy is implemented with the help of the error representation function as error indicator.
