Title: Generalized amalgamation and homology groups in model theory, part 2

Abstract: The talk will be an exposition of the series of papers by John Goodrick, Byunghan Kim, and the speaker. The papers develop the basics of homology theory in a model-theoretic context and connect it with generalized amalgamation properties. This talk will introduce definitions of homology groups H_n associated with a family of "amalgamation functors" and establish the connection between the failure of generalized amalgamation and non-triviality of the appropriate homology groups.
