Title: Conjugacy and homogeneous graphs, II
Abstract: This talk is continued from last semester. We study the conjugacy relation on the automorphism group of a homogeneous structure from the point of view of Borel complexity theory. In particular, we present three examples of homogeneous graphs whose corresponding conjugacy problems have three different complexities.
