Millican lectures are made possible through the generosity of Mr. Olin Moore Millican (1904-1999), who established the Roy McLeod Millican Memorial Fund in honor of his brother.
The talks typically take place on Mondays from 4:30 to 5:30 pm in GAB 461. The talks are intended for a general mathematical audience, and everyone is encouraged to attend (including undergraduates). Refreshments are served 30 minutes before the talk in the same room as the talk.
For more information, contact Lea Beneish.
Events for Fall 2026 - Spring 2027
Upcoming Events (AY 2026-2027)
September 28, 2026: Jackson Morrow (UNT), Fields Medal Series 1/4Title: How a subfield of logic was used to prove conjectures in arithmetic and algebraic geometryAbstract: Jacob Tsimerman received the 2026 Fields Medal for “his contribution in recasting o-minimality as a fundamental method in arithmetic and complex algebraic geometry and his role in the proof of many central conjectures…” In this talk, I will give an overview of o-minimality (which is a topic from model theory) and how Tsimerman used results and techniques from this area to prove longstanding conjectures in arithmetic and algebraic geometry. Specifically, I will focus on Tsimerman’s contributions to the resolution of the Griffiths conjecture concerning algebraicity of images of period maps. I will assume no background in algebraic geometry or model theory, and the talk will eschew details and focus on overarching ideas. |

Recent Events (AY 2026-2027)
September 14, 2026: Will Boney (Texas State University)Title: Nonstandard ultraproducts in torsion modules, perfect groups, locally finite groups, and more!Abstract: Taking ultraproducts is an essential tool in model theory, most notably giving a proof of the powerful Compactness Theorem for first-order logic: if a every finite subset of a collection of axioms has a model, then there is a model of the entire (infinite!) set of axioms. However, (working in ZFC) the standard ultraproduct construction is not very useful outside of first-order logic. On the other hand, many interesting algebraic properties are not first-order: torsion modules, locally finite groups, rank 1 valued fields, and more. |
