1. 1. Interacting particle systems in a randomly evolving environment

   Författare :Marcus M J Warfheimer; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interacting particle systems; contact process; randomly evloving environment; spin systems; Interacting particle systems;

   Sammanfattning : This thesis concerns interacting particle systems in a randomly evolving environment. In the first paper, we consider the so called contact process in a randomly evolving environment (CPREE), introduced by Erik Broman. This process is a generalization of the contact process where the recovery rate can vary between two values. LÄS MER

3. 2. Interacting particle systems in varying environment, stochastic domination in statistical mechanics and optimal pairs trading in finance

   Sammanfattning : In this thesis we first consider the contact process in a randomly evolving environment, introduced by Erik Broman. This process is a generalization of the contact process where the recovery rate can vary between two values. The rate which it chooses is determined by a background process, which evolves independently at different sites. LÄS MER
