"Model Theory of Tracial von Neumann Algebras"
This talk is the latest in a series of seminars on the model theory of C*-algebras. This week, we axiomatize tracial von Neumann algebras, tracial factors, and II\textsubscript{1} factors. We define local classes of algebras and determine whether several classes of finite factors are local and/or axiomatizable. We follow Farah, Hart, and Sherman's work in their series of papers titled “Model Theory of Operator Algebras.”

"Arens irregularity in harmonic analysis"
Arens irregularity of a Banach algebra is due to elements in its Banach dual which are not weakly almost periodic.
Jeffrey Samuelson, Department of Pure Mathematics, University of Waterloo
"Introducing affine schemes"
We will introduce the notion of an affine scheme and describe the Zariski topology, after which we will discuss several examples.

"Sidon and Kronecker-like sets in harmonic analysis"
Let $G$ be a compact abelian group and $\Gamma$ be its discrete dual group. In this thesis we study various types of interpolation sets.
