Fermat Reals: Nilpotent Infinitesimals and Infinite Dimensional Spaces
(2010-01-20)
The main aim of the present work is to start a new theory of actual infinitesimals, called theory of Fermat reals. After the work of A. Robinson on nonstandard analysis (NSA), several theories of infinitesimals have been ...
Fast Resource Sharing in VLSI Routing
(2010-02-04)
Routing is the last major step in chip design. It naturally splits into global and detailed routing: In global routing, an approximate layout of electrical connections is computed, subject to constraints on ...
Jump processes with variable scaling parameters
(2010-01-06)
The leitmotif of this thesis is non-locality. More precisely, it deals with a class of pure jump processes with space-dependent jump measures and with related non-local integrodifferential operators. Such objects arise in ...
Facility Location and Clock Tree Synthesis
(2010-04-13)
The construction of clock trees and repeater trees are major challenges in chip design. Such trees distribute an electrical clock signal from a source to a set of sinks on a chip. On recent designs there can be millions ...
Sharp interface limit for the stochastic Allen-Cahn equation
(2010-03-17)
The behavior of the Allen-Cahn equation
∂ t u ε (x,t)= Δ u ε (x,t) - ε -2 F'(u ε (x,t))+ ξ t ε
with an additional stochastic ...

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. ...
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 ...
