The numerical simulation of a three dimensional fluid sediment system on arbitrarily shaped domains
(2016-07-26)
Current driven sediment processes and their impact on the fluid system and on the morphology is of large interest in environmental as well as in engineering sciences. In this thesis both aspects are regarded. In detail, ...
On the relation between K- and L-theory of complex C*-Algebras
(2016-07-26)
We study the space of natural transformations from connective topological K-theory to algebraic L-theory viewed as functors from C*-algebras to spectra. We prove the existence of a transformation which witnesses the ...
Isogeometric Approximation of Variational Problems for Shells
(2016-05-27)
The interaction of applied geometry and numerical simulation is a growing field in the interplay of com- puter graphics, computational mechanics and applied mathematics known as isogeometric analysis. In this thesis we ...
The delta invariant in Arakelov geometry
(2016-05-24)
In this thesis we study Faltings' delta invariant of compact and connected Riemann surfaces.
This invariant plays a crucial role in Arakelov theory of arithmetic surfaces. For example, it appears in the arithmetic ...

Construction of a Rapoport-Zink space for split GU(1, 1) in the ramified 2-adic case
(2016-07-06)
Let F be a finite extension over the field of 2-adic numbers. In this paper, we construct a Rapoport-Zink-space for the split unitary group in two variables over a ramified quadratic extension of F. For this, we first ...
Essays in Statistics
(2016-03-29)
This thesis is comprised of several contributions to the field of mathematical statistics, particularly with regards to computational issues of Bayesian statistics and functional data analysis.
The first two chapters ...

Simulation of Ion Migration with Particle Dynamics and the Heat-Poisson-Nernst-Planck System
(2016-12-22)
In this thesis we study the numerical simulation of ion migration and its coupled thermal effects. Many of the existing mathematical models in this area of research implicitly rely on thermal equilibrium conditions, despite ...
Analysis of Biochemical Reaction Networks using Tropical and Polyhedral Geometry Methods
(2016-12-21)
The field of systems biology makes an attempt to realise various biological functions and processes as the emergent properties of the underlying biochemical network model. The area of computational systems biology deals ...
Low-rank Tensor Recovery
(2016-10-28)
Low-rank tensor recovery is an interesting subject from both the theoretical and application point of view. On one side, it is a natural extension of the sparse vector and low-rank matrix recovery problem. On the other ...
On Approximability, Convergence, and Limits of CSP Problems
(2016-09-16)
This thesis studies dense constraint satisfaction problems (CSPs), and other related optimization and decision problems that can be phrased as questions regarding parameters or properties of combinatorial objects such as ...
