"Plane Old Tilings"

Luke MacLean, Department of Pure Mathematics, University of Waterloo

"Ramsey's Theorem"

We will discuss two different proofs of Ramsey's Theorem and compare their reverse mathematical strength.

MC 5413

James Freitag, University of Illinois at Chicago

"Model theory, automorphic functions, and differential equations"

John Schanck, Department of Combinatorics & Optimization, University of Waterloo

"Kummer's Theorem on binomial coefficients, etc."

MC 5413

Andrew Zimmer, Louisiana State University

"Intrinsic and extrinsic geometries in several complex variables"

Henry Yuen, University of Toronto

"Connes’ Embedding Problem through the lens of complexity theory"

Boyu Li, University of Victoria

"Amenable and Non-amenable Semigroups"

Since Nica introduced the notion of amenability of quasi-lattice ordered semigroups, the amenability for many classes of semigroups remain unanswered. We will give a brief overview of semigroup amenability, and show some recent developments on this topic using dilation theory. In particular, we shall show that Artin monoids are non-amenable except the class of right-angled. This is a joint work with Marcelo Laca.

MC 5417

Dino Rossegger, Department of Pure Mathematics, University of Waterloo

"Determinacy in second order arithmetic"

Wilson Poulter, Department of Pure Mathematics, University of Waterloo

"NIP VI"

We finish section 2.2.2 of Simon's Guide to NIP theories and move on to 2.2.3.
