Mathematics Colloquium

Upcoming Colloquium

Curve counting in enumerative geometry
Dr. Reginald Anderson, UC Irvine

September 4, 2026
12:00pm-1:00pm in FO3-200A

Abstract

We give a historical introduction to curve-counting problems enumerative geometry for a general audience. We introduce three ways of counting curves: Gromov--Witten, Donaldson--Thomas, and Pandharipande--Thomas invariants. Finally, we define the notion of a generating series, state open conjectures for generating series of Pandharipande--Thomas invariants, and share some recent progress made in joint work with Dominic Joyce. All are welcome!

Biosketch

Dr. Reginald Anderson completed his PhD in the Mathematics Department at Kansas State University in May 2023 under the supervision of Gabriel Kerr. His research areas include algebraic geometry, homological algebra, and symplectic geometry. After his PhD, he was Visiting Assistant Professor at Claremont McKenna College, before starting his position as Chancellor's Postdoctoral Fellow at UC Irvine in July 2025. 

About the Colloquium

The Mathematics Colloquium is a unique opportunity for students to learn about new developments in mathematics and what mathematics and statisticians do after they graduate. Hosted by the Department of Mathematics and Statistics at California State University, Long Beach, the weekly meetings invite guests from universities, research laboratories, and industry to present and discuss current topics in mathematics. All students are encouraged to attend.

Schedule

The following schedule is for Fall 2026.
