The Algebraic Combinatorics Seminar

Weber 223

The singular locus of regular Hessenberg varieties Martha Precup Washington University in St. Louis Hessenberg varieties are subvarieties of the flag variety with important connections to representation theory, algebraic geometry, and combinatorics. Like Schubert varieties, the structure of Hessenberg varieties can be studied using the combinatorics of the symmetric group. In this talk, we will […]

PhD Preliminary Examination of Michael Moy

Weber 201

Advisor:  Dr. Henry Adams Committee:  Dr. Chris Peterson, Dr. Amit Patel, Dr. Asa Ben-Hur Title: Persistence and Metric Thickenings Abstract: This talk will cover multiple related topics in applied topology.  Persistent homology, the main tool of applied topology, is based on the algebraic theory of persistence modules.  This theory has developed over roughly the last […]

Title: "Interpolation for polynomials in two variables" Abstract: I will discuss the following problem: given n general points {p_i} in the plane, and positive integer {m_i}, what is the dimension of the space of polynomials f(x,y) of degree d having multiplicity at least m_i at p_i for each i?  Various conjectures are available for different […]

Educ8: End of Semester Meeting

Weber 15

Come join Educ8 for our last meeting of the semester! We'll have pizza, origami, and math games to have some fun and relax before finals week. We hope to see you there! Educ8 is the Math Education club at CSU. To join the mailing list, please fill out this form: https://forms.gle/fDnn7KZmW6Y3kGeDA

PhD Preliminary Examination of Vladimir Sworski

Weber 201

Advisor:  Dr. Rachel Pries Committee:  Dr. Alexander Hulpke, Dr. Mark Shoemaker, Dr Joe Gersch Title: An Exploration of the Genus 2 Superspecial (2,2)-Isogeny Graph Abstract: In 2022, one of the finalists for NIST's call for a post-quantum cryptography, SIKE, was broken by Castryck and Decru. They constructed an attack relying on the Genus 2 Superspecial […]

Applied Category Theory Seminar

Weber 201

Professor James Wilson will be giving a high-level survey of where we are going with Homotopy Type Theory this semester.

Applied Category Theory Seminar

Weber TBD

The first third of the semester will be used to prepare for Professor Emily Rheil's colloquium talk on homotopy type theory on February 20 - we will be walking through type theory - simple, dependent, identity types, and induction. Lastly, we have a new website! It's at https://csu-applied-category-theory.github.io/

The Algebraic Combinatorics Seminar

Weber 117

Talk 1: Spectral Turan problems for intersecting even cycles Dheer Desai University of Wyoming Turán numbers are a cornerstone of extremal graph theory. For graphs with chromatic number at least three, the asymptotics of the Turán numbers are completely known and follow from celebrated results of Erdős, Stone and Simonovits. However, these remain unknown for […]
