Title:Invariant measures on homogeneous structures
Seminar:Logic Seminar
Speaker:Jan Reimann, Penn State
Abstract:
Many constructions of universal homogeneous structures can be randomized. The most famous example is arguably the Rado graph, which can obtained by chosing edges randomly with probability 0 < p < 1. Other examples include the universal K_n-free graph (Petrov and Vershik), and the Urysohn space (Vershik). The existence of such a randomized construction is closely tied to the existence of a measure on the homogeneous structure that is invariant under the logic action. In this talk I will survey a number of important results on such measures.
