“Quantizing the String”

“Smoothness of convolution products of orbital measures on rank one compact symmetric spaces”

Thursday, January 14, 2016 — 3:30 PM EST

**Christopher Hawthorne, Pure Mathematics, University of Waterloo**

We will work through chapter 7 of Tent and Ziegler. We will develop the notions of forking and dividing as measures of how strongly a set depends on a set of parameters. We will then introduce simple theories, an important generalization of stable theories.

"Morita theory 1: Modules"

Let $\mathrm{Mod}_R$ be the category of right $R$-modules. Two rings $R,S$ are \textit{Morita equivalent}, denoted $R\sim S$, if $\mathrm{Mod}_R$ and $\mathrm{Mod}_S$ are equivalent as categories. For example $\mathbf{C}$ is Morita equivalent to $M_2(\mathbf{C})$, because any $\mathbf{C}$-vector space can double up to become an $M_2(\mathbf{C})$-module. Many properties are Morita invariant; for instance simplicity, semisimplicity, and chain conditions.

“2-randomness and complexity”

We will begin our proof that Z is 2-random if and only infinitely many of its initial segments are incompressible in the sense of plain complexity.

Abstract

This term we will be reading through Ducros Bourbaki article, “Les espaces Berkovich sont moderes [dapres Ehud Hrushovski et Francois Loeser]. We start with the overview given in the introduction.

“Stronger Notions of Randomness”

Last semester we studied Martin-Lof randomness, and the weaker notion of Schnorr ran- domness. We will now introduce 2-randomness and weak 2-randomness, which are stronger notions than Martin-Lof randomness.

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 promised 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.
