UA Grad Colloquium

26Fa UArizona Grad Colloquium

In fall 2026, the UA Grad Colloquium is organized by Tanner Reese. This website is maintained by Napoleon Wang.

The graduate colloquium is a weekly seminar for graduate students in math, stats, and applied math. It is an ideal environment to practice public speaking skills, connect with peers, and explore new mathematical ideas. Presentations do not need to be novel research. Participants are welcome to share any math-related topic that currently interests them.

We meet Mondays, 4–5 PM Arizona time, in Math 402, unless otherwise noted.

Here is the sign-up link for the mailing list https://list.arizona.edu/sympa/subscribe/math-grad-colloquium.

Title: p-invariants of Abelian varieties (and maybe the Torelli locus)
Abstract: Abelian varieties are higher-dimensional analogues of elliptic curves and play a central role in modern algebraic geometry and number theory. In layman's terms, they are projective varieties that have a group structure. When working over a field of positive characteristic p, the geometry of an abelian variety is influenced in interesting ways by the prime p. It is analogous to how fields of characteristic p > 0 admit inseparable field extensions and have a lot of exotic phenomena. Consequently, there is a class of invariants, called p-invariants, that can be assigned to abelian varieties over characteristic p, and a current research topic is studying which invariants are possible. In particular, one can look at the stratifications induced by the invariants and study whether they have nice geometric properties such as irreducibility, smoothness, etc.
