Finite Element Methods for Geometric Problems
(2012-10-12)
In the herewith presented work we numerically treat geometric partial differential equations using finite element methods. Problems of this type appear in many applications from physics, biology and engineering use.

Adaptive numerical simulation of contact problems: Resolving local effects at the contact boundary in space and time
(2012-10-24)
This thesis is concerned with the space discretization of static and the space and time discretization of dynamic contact problems. In particular, we derive a new efficient and reliable residual-type a posteriori error ...
United Elliptic Homology
(2012-09-11)
We study the categories of modules over real K-theory and TMF. Inspired by work of Bousfield, we consider TMF-modules at the prime 3 which are relatively free with respect to TMF(2). We show that a large class of these can ...
On rigidity of the ring spectra PmS(p) and ko
(2012-09-14)
We study the rigidity question for modules over certain ring spectra. A stable model category is rigid if its homotopy category determines the Quillen equivalence type of the model category. Amongst others, we prove that ......
Über Starrheit der Ringspektren PmS(p) and ko
Wir beschäftigen uns mit der Frage ob die Kategorie der Moduln über bestimmten Ringspektren starr sind. Eine stabile ......

The Formation of the Concertina Pattern: Experiments, Analysis, and Numerical Simulations
(2011-09-12)
The concertina is a magnetization pattern observed in elongated thin-film elements of a soft-magnetic material during the switching-process by an external magnetic field. The almost periodic pattern consists of stripe-like ...
Unbounded Bivariant K-theory and an Approach to Noncommutative Fréchet Spaces
(2011-09-19)
In the current work we thread the problems of smoothness in non-commutative $C^*$-algebras arising form the Baaj-Julg picture of the $KK$-theory. We introduce the notion of smoothness based on the pre-$C^*$-subalgebras of ...
Alternative Finestructural and Computational Approaches to Constructibility
(2011-07-14)
We consider attempts to simplify finestructural arguments concerning inner models of ZFC, in particular L; in addition, we exhibit different aspects of the computational strength of Infinite Time Register Machines....
Die Arbeit befasst sich mit alternativen Methoden zur Analyse von Gödels konstruktiblem Universum L, dem ⊆-minimalen klassenmächtigen Modell von ZFC und anderer konstruktibler Strukturen.

Mirror symmetry and stability conditions on K3 surfaces
(2011-07-20)
This thesis is concerned with questions arising in the realm of mirror symmetry for K3 surfaces. It is divided into two parts.
In the first part, we study the bijection between Fourier–Mukai partners of a K3 surface ...

Homology Computations for Mapping Class Groups, in particular for Γ03,1
(2011-09-12)
In this thesis we compute the homology of mapping class groups of orientable and non-orientable surfaces. The surfaces we consider are of genus g, have one boundary curve and m permutable punctures. The ...
Sparse Grid Methods for Higher Dimensional Approximation
(2010-09-10)
Diese Arbeit befasst sich mit Dünngitterverfahren zur Lösung von höherdimensionalen Problemen. Sie zeigt drei neue Aspekte von Dünnen Gittern auf: Erweiterungen der elementaren Werkzeuge zur Arbeit mit Dünnen Gittern, eine ...
