1. Extensional rheometry through hyperbolic contraction
Sammanfattning : To understand fluid rheology, properties such as consistency and viscosity are determined in both shear and extensional flow. Many commonly-used materials and formulations exhibit complex rheological properties and in order to determine the behaviour as well as predict and govern their properties, effective and reliable characterisation of these fluids is important.

2. Dynamics of Smooth Hyperbolic Systems with Singularities
Sammanfattning : This thesis is about dynamics of piecewise hyperbolic maps on bounded sets in the plane and on the interval. It is based on the following papers: T. Persson, A piecewise hyperbolic map with absolutely continuous invariant measure, Dynamical Systems: An International Journal, 21:3 (2006), 363--378 T. LÄS MER
3. Wavelet Solvers for Hyperbolic PDEs

4. Semi-classical approximations of Quantum Mechanical problems
Sammanfattning : .... LÄS MER
5. Arithmetic and Hyperbolic Structures in String Theory
Sammanfattning : This thesis consists of an introductory text followed by two separate parts which may be read independently of each other. In Part I we analyze certain hyperbolic structures arising when studying gravity in the vicinity of spacelike singularities (the BKL-limit). LÄS MER
