"Pseudo-finite sets and dimension, Part 8"
I'll talk about unimodularity. It was introduced by Hrushovski in early 90s as a generalisation of local finiteness. Unimodularity has recently reappeared in the pseudo-finite setting as a tool to develop intersection theory.
MC 5403.

"Etale descent"
Following the Bakker-Brunebarbe-Tsimerman paper, we show that quotients by etale equivalence relations exist for definable analytic spaces.

"Diagrammatic Methods in Topology"
A recent tool for understanding 4-manifolds is something called a “trisection.” These have the interesting advantage of changing problems about 4-manifolds to problems of combinatorics on surfaces. This talk will be an (accessible) tourist’s guide to some background and similar ideas from low(er) dimensional topology: Heegaard splittings and diagrams. Time permitting, we’ll also introduce a trisection and discuss some recent developments.

"Dualizing structures that are necessarily of infinite signature, part 3: the gory details"
In this lecture I will finish Pitkethly’s proof that her schizophrenic pair is in fact a dualizing pair. If time remains, I’ll sketch the proof that the term operations of the algebra are not determined by any finite-signature alter ego.
