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

   Författare :Hanna Oppelmayer; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Limit Theorems for Ergodic Group Actions and Random Walks

   Författare :Michael Björklund; Anders Karlsson; Yves Guivarc'h Irmar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

   Sammanfattning : This thesis consists of an introduction, a summary and 7 papers. The papers are devoted to problems in ergodic theory, equidistribution on compact manifolds and random walks on groups. In Papers A and B, we generalize two classical ergodic theorems for actions of abelian groups. LÄS MER
