“Recent Developments in Moonshine”
Hongdi Huang, Pure Mathematics, University of Waterloo
"Morita Theory IV: The Morita Context"
If $F:\mathrm{Mod}_R \rightarrow \mathrm{Mod}_S$ is a Morita equivalence, then it preserves progenerators, so $P_S:= F(R_R)$ is a progenerator in $\mathrm{Mod}_S$. We'll see that that $P_S$ has a left $R$module structure and $F\simeq \otimes _RP_S$, thus giving rise to a \textit{Morita context} between $R$ and $S$. Conversely, the existence of a Morita context implies that $R$ and $S$ are Morita equivalent.

"More on definable functors, and imaginaries"

"Donuts and Pants, then Quasiconformal Maps"
Raymond Cheng, Pure Mathematics, University of Waterloo
"Hilbert Scheme of Points on Surfaces"
Finally, we are in place to discuss the Hilbert scheme of points in a surface. We will discuss some geometric properties of this Hilbert scheme. In particular, we will attempt to explain why the Hilbert scheme of points in the affine plane is smooth and irreducible scheme. We may also give a description of this Hilbert scheme in a way suggestive for future discussions.

"A result on constraint satisfaction problems: part 3"
In this talk, I will begin going through Bulatov's proof that a nonempty standard $(2,3)$system with potatoes from a variety of $2$semilattices has a solution. It should take two lectures to complete the proof.

“Survey talk on vonNeumann algebras”
We survey some of the fundamental theory of vonNeumann algebras and their traces, while providing everyday examples. We will then talk a bit about abelian vonNeumann algebras, and their relationship to measure theory. Time permitting, we will talk about types decomposition for vonNeumann algebras.
Michael Deveau, Department of Pure Mathematics, University of Waterloo
“Bases for MLRandomness”
We briefly recall the definition of a base for MLrandomness presented last time. The remaining portion of the talk will be spent stating and proving an important result about such sets, namely that every base for MLrandomness is low for K.

Ian Payne, Department of Pure Mathematics, University of Waterloo
“A result on constraint satisfaction problems: part 4”
I will finish presenting Bulatov’s proof that a standard (2,3)system over the variety of 2semilattices has a solution, and talk about how the set of solutions has some nice properties.

“Bases for MLRandomness  Part 2”
We briefly discuss the construction presented last time, which proves that each base for MLrandomness is low for K, and then verify that the construction works as claimed. We then use this result to prove an important corollary. Time permitting, we begin a discussion about lowness pairs.

Michael Hartz, Department of Pure Mathematics, University of Waterloo
“Representations of multiplier algebras of NevanlinnaPick spaces”
NevanlinnaPick spaces are Hilbert function spaces which mirror some of the fine structure of the classical Hardy space on the unit disc. Their multiplier algebras are an important class of non selfadjoint operator algebras of functions.

"My favorite number"
The number 24 plays a central role in mathematics thanks to a series of
"coincidences" that is just beginning to be understood. One of the first
hints of this fact was Euler's bizarre "proof" that
1 + 2 + 3 + 4 + ... = 1/12

“The mean ergodic theorem, then and now”
The mean ergodic theorem, originally proved by von Neumann, was motivated by Boltzmann’s ”ergodic hypothesis”, and constitutes a cornerstone of classical ergodic theory.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
