"Uncollapsed Hrushovski constructions, part 2"

Last week, we constructed the Hrushovski-Fraisse limit of a class of finite relational structures. This week, I will axiomatize these limits and prove they are omega-stable. I will also give a characterization of forking. If time allows, I will show some potential application.

"Integrable System on Smooth Projective Toric Varieties, Part 2"

This is a continuation to my previous talk on building an integrable system on smooth projective toric varieties. In my previous talk, I explained how to view a smooth projective toric variety as a symplectic reduction. In this talk I will briefly review this construction and from here show that the torus action in our variety is Hamiltonian and explain how the integrable system is constructed.
