Stochastic individual-based models of adaptive dynamics and applications to cancer immunotherapy
(2017-03-24)
In this thesis stochastic individual-based models describing Darwinian evolution of asexual, competitive populations are studied. A specialization of these models is developed to describe tumor development under immunotherapy ...
Timing-Constrained Global Routing with Buffered Steiner Trees
(2017-08-25)
This dissertation deals with the combination of two key problems that arise in the physical design of computer chips: global routing and buffering.
The task of buffering is the insertion of buffers and inverters into ...

Couplings and Kantorovich contractions with explicit rates for diffusions
(2017-09-15)
We consider certain classes of diffusion and McKean-Vlasov processes and provide non-asymptotic quantifications of the longtime behavior using coupling methods. The thesis is divided into three main parts.
In the ...

Mesh Refinement Strategies for the Adaptive Isogeometric Method
(2017-09-01)
This thesis introduces four mesh refinement algorithms refine_hb, refine_thb, refine_ts2D and refine_tsnD ...
Universelle elliptische Gauß-Summen und der Algorithmus von Schoof
(2017-07-21)
Die vorliegende Arbeit beschäftigt sich mit verschiedenen neuen Ansätzen im Kontext des Punktezählens auf elliptischen Kurven über endlichen Primkörpern mit großer Charakteristik. Sie baut dabei auf der Grundidee von Schoof ...
Relative unitary RZ-spaces and the Arithmetic Fundamental Lemma
(2017-03-29)
We verify new cases of the Arithmetic Fundamental Lemma (AFL) of Wei Zhang. This relies on a recursive algorithm which allows, under certain conditions, to reduce the AFL identity in question to an AFL identity in lower ...
Zero Partition Cycles: A Recursive Formula for Characteristic Classes of Surface Bundles
(2017-04-25)
This thesis is concerned with characteristic classes of surface bundles. A complete description of the ring of stable rational characteristic classes is given by the work of Madsen and Weiss as the polynomial ring in the ...
Class forcing and second-order arithmetic
(2017-04-24)
We provide a framework in a generalization of Gödel-Bernays set theory for performing class forcing. The forcing theorem states that the forcing relation is a (definable) class in the ground model (definability lemma) and ...
Modeling and Simulation of cracks and fractures with peridynamics in brittle materials
(2017-04-24)
Today, ceramic materials are an essential component of batteries for electric cars. One key feature of this kind of battery is the safety of the ceramic core. Here, the precise approximation of the evolution of damage after ...
A phase-field model of dislocations on parallel slip planes
(2017-03-10)
We expand the Peierls-Nabarro phase-field model of dislocations on one active slip plane introduced by Koslowski, Cuitiño, and Ortiz to the case of multiple parallel slip planes embedded into a homogeneous anisotropic ...
