1. Analysis of Adaptive Finite Element Methods
Abstract : This thesis is concerned with the analysis and design of adaptive finite element methods for a variety of differential equations in mechanics and physics, including linear and semilinear elliptic equations, eigenvalue problems, the stationary Navier-Stokes equations, and Hamiltonian systems. The analysis focuses on sharp a posteriori error estimates, sharp a priori error estimates, stability properties, and the design of adaptive algorithms. READ MORE

2. Contributions to Modelling and Visualisation of Multibody Systems Simulations with Detailed Contact Analysis
Abstract : The steadily increasing performance of modern computer systems is having a large influence on simulation technologies. It enables increasingly detailed simulations of larger and more comprehensive simulation models. Increasingly large amounts of numerical data are produced by these simulations. READ MORE

3. Reliable hp finite element computations of scattering resonances in nano optics
Abstract : Eigenfrequencies are commonly studied in wave propagation problems, as they are important in the analysis of closed cavities such as a microwave oven. For open systems, energy leaks into infinity and therefore scattering resonances are used instead of eigenfrequencies. READ MORE

4. Duality-based adaptive finite element methods with application to time-dependent problems
Abstract : To simulate real world problems modeled by differential equations, it is often not sufficient to consider and tackle a single equation. Rather, complex phenomena are modeled by several partial dierential equations that are coupled to each other. READ MORE
