Statistics Seminars: Phase transitions in a class of infinite particle systems

Presented by Alex Daletskii, York University

9 February 2015 14:00 in CM221

We study infinite (random) systems of interacting particles living in a
Euclidean space X and possessing internal parameter (spin) in R 1. Such
systems are described by Gibbs measures on the space (X; R 1 ) of marked
configurations in X (with marks in R 1). For a class of pair interactions, we
show the occurence of pase transition, i.e. non-uniqueness of the correspond-
ing Gibbs measure, in both 'quenched' and 'annealed' counterparts of the
model.
