A classification of localizing subcategories by relative homological algebra
(20151217)In this thesis, we use the tools of relative homological algebra in triangulated categories to define a sensible notion of support for objects in the bootstrap class of a Kasparov category of C*algebras over a finite ... 
A colimit construction for groupoids
(20160803)We consider Ore monoid actions in a certain bicategory of étale groupoids Gr_prop. Examples of such actions include selfsimilar groups, higher rank graphs and actions of Ore monoids on spaces by topological correspondences. ... 
An Integration Theorem for Representations of the Tangent Algebroid
(20240209)This dissertation investigates representations of Lie groupoids and Lie algebroids and the connection between them. Lie groupoids and Lie algebroids are differentialgeometric generalisations of Lie groups and Lie ... 
C*quantum groups with projection
(20140625)We propose a general theory to study semidirect products of C quantum groups in the framework of multiplicative unitaries. Starting from a quantum group with a projection we decompose its multiplicative unitary as a product ... 
Coarse Geometry for Noncommutative Spaces
(20161123)We develop an analogoue of coarse geometry for noncommutative spaces in terms of unitizations of the given C* algebra. Examples for our theory come from Rieffel deformation of compactifications under strongly continuous ... 
Exakte Moduln über dem von Manuel Köhler beschriebenen Ring
(20181113)When proving an equivariant universal coefficient theorem for C*Algebras acted on by a finite cyclic group Z/pZ, Manuel Köhler introduces the endomorphism ring R of the tuple (C,C(G),D). The aim of this thesis is to show ... 
Explicit GL(2) trac formulas and uniform, mixed Weyl laws
(20121024)This thesis provides an explicit, general trace formula for the Hecke and Casimir eigenvalues of GL(2)automorphic representations over a global field. In special cases, we obtain Selberg's original trace formula. Computations ... 
Groupoids in categories with partial covers
(20190207)Meyer and Zhu survey the general theory of groupoids, groupoid actions, groupoid principal bundles, and various kinds of morphisms between groupoids in the framework of categories with pretopology. We modify the categorical ... 
Index theory and groupoids for filtered manifolds
(20201221)In this thesis, we propose to use generalized fixed point algebras as an approach to the pseudodifferential calculus on filtered manifolds. A filtered manifold is a manifold \(M\) with a filtration of its tangent ... 
Noncommutative manifolds and SeibergWittenequations
(20111017)In this thesis we study differential geometry of noncommutative manifolds. We introduce a general framework of noncommutative manifolds based on Poincaré duality and study the notions of differential forms and Sobolev ... 
On C*algebras associated to product systems
(20180517)We consider a class of Fell bundles over quasilattice ordered groups. We show that these are completely determined by the positive fibres and that their cross sectional C*algebras are relative Cuntz–Pimsner algebras ... 
Topological construction of C*correspondences for groupoid C*algebras
(20150909)Let G and H be locally compact, Hausdor groupoids with Haar systems. We de fine a topological correspondence from G to H to be a GH bispace X carrying a Gquasi invariant and Hinvariant family of measures. We show that ... 
Topological Invariants for NonArchimedean Bornological Algebras
(20201013)In this thesis, we define a cyclic homology theory for nonarchimedean bornological algebras, which we call analytic cyclic homology. Let V be a complete, discrete valuation ring with uniformiser p, residue field k, and ... 
Universal Coefficient Theorems in Equivariant KKtheory
(20110221)We prove a universal coefficient theorem for C*algebras acted upon by a group of prime power order. In this context, we define an extension of equivariant Ktheory and prove the existence ... 
Über J. Bernsteins zweite Adjungiertheit für reduktive padische Gruppen
(20221025)We give a new and essentially elementary proof of an important result due to Joseph Bernstein in the theory of smooth representations of a reductive padic group G. Main tools for studying these representations are parabolic ...
