"A trick involving biduals and an application"
I will present a trick involving biduals of C* algebras and present an application that derives proper proximality of all wreath products where the acting group is non amenable. This is joint work with Changying Ding.
This seminar will be held jointly online and in person:

"Stability Properties of Quasiregular Curves"
I will discuss a family of maps called Quasiregular curves that are generalizations of quasiconformal maps and holomorphic curves. I will present their basic properties and present some recent work. Mainly, if a quasiregular curve satisfies a small distortion property, then it can be approximated by a Möbius transformation. This talk is based on joint work with Susanna Heikkilä and Pekka Pankka.

"Developing Connections through Rich Mathematical Problems"
In this informal and interactive workshop, Richard will present three puzzles, and share stories of how these problems have led to authentic mathematical experiences for his students. In the process of solving these puzzles together, we will uncover how these problems link key undergraduate topics taught in the Faculty of Mathematics. Finally, we will explore how we might integrate inquiry-driven problem-solving into all of our courses.
