"Exact Formulas for Averages of Secular Coefficients"

We present formulas for averages, over the classical compact groups, of the coefficients of powers of characteristic polynomials. The study of these coefficients was motivated by connections with analogous problems in number theory dealing with averages of divisor sums over short intervals.

"Applications of the minimal model program in arithmetic dynamics"

Arithmetic dynamics is a rapidly growing field of mathematics that lies in the intersection of algebraic geometry, number theory and complex dynamics. Many interesting number theoretic problems admit a dynamical generalization. Understanding this dynamical generalization can shed new light on the original problem while also leading to new and interesting challenges in arithmetic and geometry.

"Monogenic Forms and Decomposition of Spinor-Valued Forms"

In this talk, we follow the text by Delanghe, Sommen, and Souček and demonstrate a splitting of the space of spinor-valued forms. We describe some important operators and their identities as well as properties of the exterior covariant derivative when restricted to certain subspaces of spinor-valued forms. Time permitting, we will define monogenic forms and some of their homological properties.

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 co-ordinated within our Office of Indigenous Relations.
