Curvature-Dimension Bounds and Functional Inequalities: Localization, Tensorization and Stability
(2010-03-16)
This work is devoted to the analysis of abstract metric measure spaces (M,d,m) satisfying the curvature-dimension condition CD(K,N) presented by Sturm and in a similar form by Lott and Villani.
In the first part, we ...

Homotopy theory of s-bimodules, naive ring spectra and stable model categories
(2010-02-01)
We study the homotopy theory of S-bimodules which essentially sequential spectra which admit a left and right action of the sphere specturm in a compatible way. The resulting category has non-symmetric monoidal product. ...
Efficient Algorithms for Routing a Net Subject to VLSI Design Rules
(2020-12-17)
In this thesis we consider detailed routing, an important step in the design of integrated circuits. On large instances detailed routing requires packing millions of node-disjoint Steiner trees into a graph with hundreds ......
Probabilistic and differential geometric methods for relativistic and Euclidean Dirac and radiation fields
(2020-07-09)
The main objective of the thesis is to study relativistic and Euclidean Fermionic quantum fields from a geometrical and probabilistic point of view as opposed to the standard treatment which is more algebraic in nature.
Gradient Flows, Metastability and Interacting Particle Systems
(2020-06-19)
Many stochastic models exhibit a phenomenon called metastability. The first goal of this thesis is to study this phenomenon for certain classes of interacting particle systems. The second goal of this thesis is the following. ...
Centralisers of polynomially growing automorphisms of free groups
(2013-07-31)
The main theorem of this thesis asserts that many centralisers in the automorphism groups Aut(F_n) and Out(F_n) of the free group F_n satisfy finiteness property VF, i.e. these centralisers have a finite index subgroup ...
Rigidity in equivariant stable homotopy theory
(2013-08-07)
For any finite group G, we show that the 2-local G-equivariant stable homotopy category, indexed on a complete G-universe, has a unique equivariant model in the sense of Quillen model categories. This means that the ...
The Farrell-Jones conjecture for some general linear groups
(2013-07-10)
In this thesis I prove the K- and L-theoretic Farrell-Jones conjecture with coefficients in any additive category for the general linear groups of F(x) for a finite field F. I also show that the general linear groups over ...
Three models of ordinal computability
(2013-05-07)
In this thesis we expand the scope of ordinal computability, i.e., the study of models of computation that are generalized to infinite domains. The discipline sets itself apart from classical work on generalized recursion ...
Energieskalierung, Gebietsverzweigung und SO(2)-Invarianz in einem fest-fest Phasenübergangsproblem
(2013-10-28)
In den frühen 90er Jahren haben Robert Kohn und Stefan Müller ein Modell entwickelt, das Musterbildung in martensitischen Formgedächtnismetallen erklären konnte. In dieser Arbeit wird eine vektorwertige Verallgemeinerung ...
