1. On the existence of complex-valued harmonic morphisms
Sammanfattning : This thesis consists of 4 papers, their content is described below: Paper I. We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. LÄS MER
2. 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
3. Holomorphic automorphisms of Danielewski surfaces
Sammanfattning : In this thesis we define the notion of an overshear on a Danielewskisurface. Next we show that the group generated by the overshears is dense in the component of the identity of the automorphism group. LÄS MER
4. Geometric control methods for nonlinear systems and robotic applications
Sammanfattning : .... LÄS MER
5. Application of Differential Geometry to Elasticity and Corresponding Discrete Models
Sammanfattning : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. LÄS MER
