1. On random satisfiability and optimization problems
Sammanfattning : In Paper I, we study the following optimization problem: in the complete bipartite graph where edges are given i.i.d. weights of pseudo-dimension q>0, find a perfect matching with minimal total weight. LÄS MER
2. Harmonic measure on random fractals
Sammanfattning : .... LÄS MER
3. Random Geometry and Reinforced Jump Processes
Sammanfattning : This thesis comprises three papers studying several mathematical models related to geometric Markov processes and random processes with reinforcements. The main goal of these works is to investigate the dynamics as well as the limiting behaviour of the models as time goes to infinity, the existence of invariant measures and limiting distributions, the speed of convergence and other interesting relevant properties.

4. Aspects of Spatial Random Processes
Sammanfattning : This thesis consists of five papers dealing with various aspects of spatial random processes. In the first three papers the main focus is on a special class of such processes, namely measures of maximal entropy for subshifts of finite type. LÄS MER
5. Stochastic systems with locally defined dynamics
Sammanfattning : We study three different classes of models of stochastic systems with locally defined dynamics. Our main points of interest are the limiting properties and convergence in these models. The first class is the locally interactive sequential adsorption, or LISA, models. LÄS MER
