Symmetric Models, Singular Cardinal Patterns, and Indiscernibles
(2012-03-12)
This thesis is on the topic of set theory and in particular large cardinal axioms, singular cardinal patterns, and model theoretic principles in models of set theory without the axiom of choice (ZF).

Dynamical and Mechanistic Effects of High Pressure Fluids in the Earth's Crust
(2012-03-16)
Overpressurized fluids in the lithosphere play a significant role in a diverse range of globally observed natural hazards. Their occurrence during volcanic eruptions or earth degassing processes is apparent, but their ...
Perfectoid spaces
(2012-03-09)
We introduce a certain class of so-called perfectoid rings and spaces, which give a natural framework for Faltings' almost purity theorem, and for which there is a natural tilting operation which exchanges characteristic ......
Factorable Groups and their Homology
(2011-07-04)
In this thesis we introduce the class of factorable groups. These are normed groups together with a norm preserving decemposition (or factorization) of each group element into two factors.
Already the norm alone ...

Multiscale Analysis of Adaptive Population Dynamics
(2012-01-11)
In this thesis we study a spatial population model based on a class of interacting locally regulated branching processes. The results consist of three parts which are independent of each other. The first part, which is the ...
Über die Nullstellen der Dirichletschen L-Funktionen und die kleinste Primzahl in einer arithmetischen Progression
(2011-11-23)
Seien a und q teilerfremde, positive natürliche Zahlen. Linnik bewies 1944, dass die kleinste Primzahl in einer arithmetischen Progression a modulo q kleiner als Cq^L mit positiven Konstanten C und L ist. Linnik selbst gab ...
Vector bundles on degenerations of elliptic curves and Yang-Baxter equations
(2011-11-15)
In this thesis, we study connections between vector bundles on degenerations of elliptic curves and the classical, quantum and associative Yang-Baxter equation. Let g denote n by n traceless matrices and let U denote the ...
On the theory of derivators
(2011-10-27)
In Part 1, we develop some aspects of the theory of derivators, pointed derivators, and stable derivators. As a main result, we show that the values of a stable derivator can be canonically endowed with the structure of a ...
Euler characteristics and geometric properties of quiver Grassmannians
(2011-10-21)
The quiver Grassmannian is the projective variety of subrepresentations of a finite-dimensional representation of a quiver with a fixed dimension vector.
Quiver Grassmannians occur naturally in different contexts. ...

The Zinger deformation of differential equations with maximal unipotent monodromy
(2011-10-28)
In this thesis, in the first part we study the Zinger deformation for the holomorphic solution of a differential equation with maximal unipotent monodromy. It is basically a generalization of the example made by Zinger, ...
