Title:Invariant measures on homogeneous structures
Seminar:Logic Seminar
Speaker:Jan Reimann, Penn State
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.
