1. Harmonic morphisms, Hermitian structures and symmetric spaces
Sammanfattning : A harmonic morphism is a map between two Riemannian manifolds with the property that its composition with a local harmonic function on the codomain is a local harmonic function on the domain. Such a map is automatically a harmonic map, satisfying an additional partial conformality condition called horizontal (weak) conformality. LÄS MER
2. Singular Integrals and Multipliers on Real and Symmetric Spaces
Sammanfattning : .... LÄS MER
3. Tight maps, a classification
Sammanfattning : This thesis concerns the classification of tight totally geodesic maps between Hermitian symmetric spaces of noncompact type. In Paper I we classify holomorphic tight maps. We introduce a new criterion for tightness of Hermitian regular subalgebras. LÄS MER
4. Strings, Branes and Non-trivial Space-times
Sammanfattning : This thesis deals with different aspects of string and /p/-brane theories. One of the motivations for string theory is to unify the forces in nature and produce a quantum theory of gravity. /p/-branes and related objects arise in string theory and are related to a non-perturbative definition of the theory.

5. 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.
