1. Amenable-like properties of étale groupoids
Sammanfattning : This thesis consists of three papers related to analytic and representation theoretic properties of étale groupoids.In the first paper, we characterize algebraically the type I and CCR property for ample groupoids and their non-commutative duals: Boolean inverse semigroups. Our results use and generalize Thoma’s work on discrete groups. LÄS MER
2. The type I and CCR properties for groupoids and inverse semigroups
Sammanfattning : This licentiate thesis consists of one paper about unitary representationtheory of ample groupoids and semigroups together with generalizationsto étale and non-Hausdorff groupoids. In the paper we study algebraically the type I and CCR properties forample Hausdorff groupoids. LÄS MER
3. Gelebte Mehrsprachigkeit im Plattenbau : Untersuchungen von Narrativen und Praktiken russlanddeutscher junger Erwachsener
Sammanfattning : This thesis focuses on the lived multilingualism of a group of young Russian-German adults who as children migrated together with their families from post-Soviet states to the Federal Republic of Germany during the 1990s. Today these adults live in a ‘Plattenbau’ housing estate in a small town in one of the new federal states of Germany. LÄS MER

5. Vector-valued Modular Forms, Computational Considerations
Sammanfattning : In the following thesis we give a thorough self-contained introduction to vector-valued modular forms with an eye to representation theoretic aspects. We also examine the mathematical details of an implementation that we provide for an algorithm that computes bases of certain spaces of vector-valued modular forms in terms of a theorem due to Raum and Xià.
