2. 1. Making Pairs

   Author : Jens Gudmundsson; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; equilibrium; existence; Pairing; matching; stability; algorithms;

   Abstract : This thesis makes a contribution to matching theory. It consists of five self-contained papers. It is a study predominately on the existence of stable outcomes. These are desirable both from a practical and a theoretical standpoint. READ MORE

4. 2. Random walk boundaries: their entropies and connections with Hecke pairs

   Author : Hanna Oppelmayer; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson boundary; Hecke pairs; Non-singular dynamical systems; Schlichting completion; random walks on groups; non-monotone sequences of $ sigma$-algebras; Furstenberg entropy;

   Abstract : We present three papers in non-singular dynamics concerning boundaries of random walks on locally compact, second countable groups. One common theme is entropy. Paper II and III are concerned with boundary entropy spectra, while Paper I studies topological properties of entropy. READ MORE

5. 3. Identifying Risk Genes for Cervical Cancer : Using Affected Sib-Pairs and Case-Control Materials from Sweden

   Author : Malin Engelmark; Ulf Gyllensten; Dan Holmberg; Uppsala universitet; []
   Keywords : Medicine; Cervical cancer; HPV; Affected sib-pairs; HLA; Fas; Genomewide scan; 9q32; TSCOT; Medicin;

   Abstract : Cervical cancer is a multifactorial disease. Infection by oncogenic types of the human papillomavirus (HPV) is the major environmental risk factor and host genetic susceptibility also influences disease development. The aim of this thesis is to identify and analyse risk genes involved in the genetic predisposition to cervical carcinoma. READ MORE

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

   Author : Marcus M J Warfheimer; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interacting particle systems; contact process; randomly evolving environment; spin systems; Ising model; fuzzy Potts model; pairs trading; optimal stopping; contact process;

   Abstract : 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. READ MORE

7. 5. Infinite-dimensional Lie bialgebras and Manin pairs

   Author : Stepan Maximov; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Manin triple; classical twist; r-matrix; Lie bialgebra; loop algebra; Yang-Baxter equation; Manin pair;

   Abstract : This PhD thesis is devoted to the theory of infinite-dimensional Lie bialgebra structures as well as their close relatives such as r-matrices and Manin pairs. The thesis is based on three papers. Paper I. READ MORE
