On quotients of ω* and automorphisms of P(ω)/fin that preserve or invert the shift
(2016-05-30)The first part of the dissertation concerns the space ω*:=βω\ω and its quotients. A 2002 result from Bella, Dow, Hart, Hrusak, van Mill and Ursino implies that homeomorphisms between 0-dimensional second-countable Hausdorff ... -
On Rho Invariants of Fiber Bundles
(2009-07-21)Using adiabatic limits of Eta invariants, Rho invariants of the total space of a fiber bundle are investigated. One concern is to formulate the aspects of local index theory for families of Dirac operator in terms of the ... -
On rigidity of the ring spectra PmS(p) and ko
(2012-09-14)We study the rigidity question for modules over certain ring spectra. A stable model category is rigid if its homotopy category determines the Quillen equivalence type of the model category. Amongst others, we prove that ... -
On some Geometric Search Problems: Algorithms, Complexity, Computability
(2020-11-25)This thesis considers four search problems which are related to or emerge from a geometric context. Each search problem is examined in a separate chapter; these four chapters are framed by an introduction and a conclusion ... -
On Some Rigidity Properties in PDEs
(2014-04-16)This thesis is dedicated to the study of three rigidity properties arising in different partial differential equations: (1) the backward uniqueness property of the heat equation in two-dimensional conical domains, (2) the ... -
On some variational problems in geometry
(2018-08-28)In this thesis we consider several variational problems in geometry that have a connection to the spectrum of the Laplacian acting on functions. In the first part, we study a quantity called the analytic systole, which was ... -
On steady Kähler-Ricci solitons
(2021-08-26)In this thesis we study the existence and uniqueness of steady Kähler-Ricci solitons. We consider two classes of manifolds on which we obtain new examples of steady solitons by using different methods for each class. In ... -
On Supporting Interoperability between RDF and Property Graph Databases
(2021-05-18)Over the last few years, the amount and availability of machine-readable Open, Linked, and Big data on the web has increased. Simultaneously, several data management systems have emerged to deal with the increased amounts ... -
On the Classification of Cohomology Bott Manifolds
(2013-11-07)We study cohomology Bott manifolds by means of modified surgery theory. Cohomology Bott manifolds admit a ring isomorphism to the cohomology ring of a Bott manifold which preserves the Pontrjagin and Stiefel-Whitney classes. ... -
On the dynamics of correlations in Scaling limits of interacting particle systems
(2018-07-09)In this work, we analyze the properties of two-particle correlations in the weak-coupling and plasma limit of interacting particle systems motivated by Bogolyubov's formal derivation of kinetic equations.
We prove ... -
On the ecology and biogeography of alpine tundra arachnids
(2014-05-21)In the course of the discussion about the effects of manmade Climate Change on ecosystems, alpine regions of the earth have become a major focus. Alpine ecosystems are generally considered to be especially sensitive towards ... -
On the effective properties of suspensions
(2019-02-04)Einstein's formula for the viscosity of dilute suspensions describes how rigid particles immersed in a Stokes-fluid increase its macroscopic viscosity in terms of the particle volume density ∅. However, up to now, a rigorous ... -
On the enigmatic mechanism of signal transduction of "arrestin-biased" angiotensin peptides: spotlight on endogenous angiotensin 1-7
(2024-02-27)(noch nicht zugänglich / not yet accessible) -
On the Feynman-Kac formula for Schrödinger semigroups on vector bundles
(2011-05-11)In this thesis we generalize the Feynman-Kac 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
(2018-07-20)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
(2018-12-13)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 G-bundles over Riemann surfaces
(2014-01-27)In this thesis, we study the moduli spaces M_(g,q)^m (G)of flat pointed principal G-bundles 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 imidazole-2-thione-based route to tricyclic 1,4-diphosphinines: synthesis, structures and reactions
(2018-02-15)The PhD Thesis “On the imidazole-2-thione-based route to tricyclic 1,4-diphosphinines: synthesis, structures and reactions” describes the synthetic concept to and first studies on the chemistry of novel tricyclic ... -
On the importance of meteorological parameters in processes affecting the chemical composition of the tropsphere
(2022-12-22)Investigating the interaction of meteorology and chemistry in the troposphere is important for the identification of the processes which drive the evolution of tropospheric composition in a changing climate. It does not ... -
On the Influence of Cations in Non-Aqueous Electrochemistry
(2019-07-29)In this thesis, different aspects of the electrochemistry in non-aqueous electrolytes are presented. Electrochemistry in non-aqueous electrolytes plays a key role in the transition from conventional to renewable energy ...
