1. Efficient Solvers for Space-Time Discontinuous Galerkin Spectral Element Methods
Abstract : In this thesis we study efficient solvers for space-time discontinuous Galerkin spectral element methods (DG-SEM). These discretizations result in fully implicit schemes of variable order in both spatial and temporal directions. READ MORE

2. Multigrid Preconditioners for the Discontinuous Galerkin Spectral Element Method : Construction and Analysis
Abstract : Discontinuous Galerkin (DG) methods offer a great potential for simulations of turbulent and wall bounded flows with complex geometries since these high-order schemes offer a great potential in handling eddies. Recently, space-time DG methods have become more popular. READ MORE

3. Finite Difference and Discontinuous Galerkin Methods for Wave Equations
Abstract : Wave propagation problems can be modeled by partial differential equations. In this thesis, we study wave propagation in fluids and in solids, modeled by the acoustic wave equation and the elastic wave equation, respectively. READ MORE

4. Spectral/hp Discontinuous Galerkin Methods for Computational Hydraulics
Abstract : We present the concept of spectral/hp element methods, i.e. finite element methods of arbitrarily (high) polynomial order, and apply the methods to computational hydraulics. READ MORE

5. On discontinuous Galerkin multiscale methods
Abstract : In this thesis a new multiscale method, the discontinuous Galerkin multiscale method, is proposed. The method uses localized fine scale computations to correct a global coarse scale equation and thereby takes the fine scale features into account. READ MORE
