"Global theory of algebraic number fields"

In this talk, I will embark on an informal review of the global theory of algebraic number fields: integrality, discriminants and integral bases, Dedekind domains, fractional ideals and the ideal class group, Minkowski theory, Dirichlet's unit theorem, splitting of primes, as time permits. Motivation for class field theory will be discussed.

"Hilbert's Syzygy Theorem"

Stanley Yao Xiao, Pure Mathematics, University of Waterloo

"Introduction to Bhargavaology"

In this introductory talk I aim to give a sampling of the vast web of important theorems related to Manjul Bhargava, one of the four Fields Medalists of 2014, and describe their importance in the context of modern number theory. There are no technical details in the talk, making it very accessible.

"Larose's theorem"

Putting together some of the machinery developed this term, I will prove Larose’s Theorem: if X is a finite, connected reflexive digraph and X admits a Taylor operation, then for every k ≥ 1, the k-th homotopy group of X is trivial.

“WDVV equations and Ramanujan identities”

In this talk I will explain why the ancestor GW correlation functions for an elliptic orbifold are quasi-modular forms.
