On the FeynmanKac formula for Schrödinger semigroups on vector bundles
Güneysu, Batu (20110511)In this thesis we generalize the FeynmanKac formula to semigroups that correspond to Schrödinger type operators with possibly singular potentials on vector bundles over noncompact Riemannian manifolds.
This ... 
On the Finiteness of the Classifying Space for Virtually Cyclic Subgroups
von Puttkamer, Timm Wilhelm (20180720)This thesis mainly deals with finiteness properties of the classifying space for the family of virtually cyclic subgroups. We establish a link between the finiteness of the classifying space and the conjugacy growth invariant ... 
On the geometry of nodal sets and nodal domains
Georgiev, Bogdan (20181213)In the present work, we study and prove results related to the nodal geometry of Laplacian eigenfunctions on closed Riemannian manifolds, as well as solutions to more general classes of elliptic partial differential ... 
On the Hilbert uniformization of moduli spaces of flat Gbundles over Riemann surfaces
Stein, Luba (20140127)In this thesis, we study the moduli spaces M_(g,q)^m (G)of flat pointed principal Gbundles over Riemann surfaces X. The genus of X is g 0 and G is a fixed Lie group. Further, we are given m 0 permutable marked points in ... 
On the imidazole2thionebased route to tricyclic 1,4diphosphinines: synthesis, structures and reactions
Koner, Abhishek (20180215)The PhD Thesis “On the imidazole2thionebased route to tricyclic 1,4diphosphinines: synthesis, structures and reactions” describes the synthetic concept to and first studies on the chemistry of novel tricyclic ... 
On the Influence of Cations in NonAqueous Electrochemistry
Reinsberg, Philip Heinrich (20190729)In this thesis, different aspects of the electrochemistry in nonaqueous electrolytes are presented. Electrochemistry in nonaqueous electrolytes plays a key role in the transition from conventional to renewable energy ... 
On the notion of order in the stable module category
Langer, Martin (20091222)The notion of order in triangulated categories, as introduced by Schwede, is investigated in the case of the stable category of kGmodules, where k is a field of characteristic p and G is a ... 
On the origin and nature of brown dwarfs and massive planets
Thies, Ingo (20110302)In this thesis the apparent peculiarities of brown dwarfs (BDs) are pointed out which force us to treat them as a population apart from, but yet still related to the stellar population. In particular, the properties that ... 
On the probabilistic evaluation of decadal and paleoclimate model predictions
Stolzenberger, Sophie (20171127)The development of climate prediction systems for years to decades is an area of current research, as these time scales are important e.g. for the planning horizon of decisionmakers. Those prediction systems can be improved ... 
On the relation between K and Ltheory of complex C*Algebras
Land, Markus (20160726)We study the space of natural transformations from connective topological Ktheory to algebraic Ltheory viewed as functors from C*algebras to spectra. We prove the existence of a transformation which witnesses the ... 
On the relaxation of a variational principle for the motion of a vortex sheet in perfect fluid
Loeschcke, Christian (20130314)A certain twophase model is considered, which stands some relation with a description of the vortex sheet configuration in a perfect fluid.
Both a sharp and a relaxed version of the evolution can be understood as ... 
On the stability of the blowup for the wave maps and the cubic wave equation
Chatzikaleas, Athanasios (20180716)In Thesis is divided into two parts. In the first part, we study the stability of the blowup for the wave maps equation whereas in the second part we address the stability of the blowup for the cubic wave equation in ... 
On the theory of derivators
Groth, Moritz (20111027)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 ... 
On the theory of higher Segal spaces
Walde, Tashi (20201021)This thesis contains three chapters, each dealing with one particular aspect of the theory of higher Segal spaces introduced by Dyckerhoff and Kapranov:
(1) By exhibiting the simplex category as an ∞categorical ... 
On the Γconvergence of the energies and the convergence of almost minimizers in infinite magnetic cylinders
Harutyunyan, Davit (20120723)In this thesis we study static 180 degree domain walls in infinite thin magnetic wires with either a rectangular or a centrally symmetric Lipschitz cross section. We explore the magnetization energy minimization problem ... 
On Topological String Theory with CalabiYau Backgrounds
Haghighat, Babak (20091123)String theory represents a unifying framework for quantum field theory as well as for general relativity combining them into a theory of quantum gravity. The topological string is a subsector of the full string theory ... 
On τTilting Theory and Perpendicular Categories
Ricke, Charlotte (20161104)We extend the classification of finitely generated modules and the combinatorial description of AuslanderReiten sequences for finitedimensional string algebras to infinite dimensional completed string algebras. The proof ...
