Special Session on Algebraic and Enumerative Combinatorics
-
Saturday April 6, 2024, 8:30 a.m.-11:00 a.m.
Special Session on Algebraic and Enumerative Combinatorics, I
Enumerative combinatorics aims to count discrete structures. Algebra is routinely useful for obtaining counting formulas, and conversely, the study of algebraic structures can often be advanced by enumerative techniques. This is why algebraic and enumerative combinatorics developed in tandem over the past half century. Our special session will bring together mathematicians interested in modern directions in algebraic and enumerative combinatorics, giving them an opportunity to share their latest research with the broader mathematical community.
