Combinatorics Seminar-Twisting Preregular Forms by 2-Cocycles
Friday, 9/9/2022, 8:00pm - 11:59pm
Title: Twisting Preregular Forms by 2-Cocycles
Speaker: Charlotte Ure, UVA
Date and time: Friday, September 9, 4–5 pm
Place: Rome 204
Abstract: As a dual notion to Drinfeld twists, the cocycle twist of a Hopf algebra is obtained by deforming the algebra structure. Furthermore, if the Hopf algebra acts on an algebra, one may twist the algebra by the same cocycle. In this talk, I will explain how this procedure relates to the construction of superpotential algebras associated to preregular forms and their Manin’s universal quantum groups.
Combinatorics and Algebra Seminar-The Sticky Matroid Conjecture
Wednesday, 7/6/2022, 7:00pm - 11:59pm
Title: The Sticky Matroid Conjecture
Speaker: Jaeho Shin, Korean Institute for Advanced Study
Date and time: Wednesday, July 6, 3-4 pm
Place: Phillips 736
Abstract: We show Kantor's conjecture (1974) holds in rank 4. This proves both the sticky matroid conjecture of Poljak and Turzík (1982) and the whole Kantor's conjecture, due to an argument of Bachem, Kern, and Bonin, and an equivalence argument of Hochstättler and Wilhelmi, respectively.
Friday, 4/29/2022, 7:00pm - 11:59pm
Title: Random Groups in Combinatorics and Number Theory and Cokernels of Random Matrices
Speaker: Nathan Kaplan, UC Irvine
Date and time: Friday, April 29, 3–4 pm
Place: Phillips 736
Abstract: How many sublattices of Zn have index at most X? If we choose such a lattice Λ at random, what is the probability that Zn/Λ is cyclic? Now let R be a random subring of Zn. What is the probability that Zn/R is cyclic?
