1. Asymptotic Problems on Homogeneous Spaces
Sammanfattning : This PhD thesis consists of a summary and five papers which all deal with asymptotic problems on certain homogeneous spaces. In Paper I we prove asymptotic equidistribution results for pieces of large closed horospheres in cofinite hyperbolic manifolds of arbitrary dimension. LÄS MER
2. Studies on boundary values of eigenfunctions on spaces of constant negative curvature
Sammanfattning : This thesis consists of two papers on the spectral geometry of locally symmetric spaces of Riemannian and Lorentzian signature. Both works are concerned with the idea of relating analysis on such spaces to structures on their boundaries.The first paper is motivated by a conjecture of Patterson on the Selberg zeta function of Kleinian groups.

3. Some applications of representation theory in homogeneous dynamics and automorphic functions
Sammanfattning : This thesis consists of an introduction and five papers in the general area of dynamics and functions on homogeneous spaces. A common feature is that representation theory plays a key role in all articles. LÄS MER
4. Moments on a City Bus : Micro-sociology of Non-verbal Interaction in Urban Bus-riding
Sammanfattning : This thesis seeks to contribute to research on social interaction in public (and semi-public) places in general, and research on non-verbal mundane interaction in these places in particular. By paying empirical attention to the non-verbal interaction that takes place in the context of riding a city bus – which is a contained and time-limited form of social activity – this thesis explores the theoretically rich source of information about mundane interaction that this specific social activity offers.

5. An Immersed Finite Element Method and its Application to Multiphase Problems
Sammanfattning : Multiphase flows are frequently encountered in many important physical and industrial applications. These flows are usually characterized by very complicated structure that involves free moving surfaces inside the fluid domain and discontinuous or even singular material properties of the flow.
