Algebra & Combinatorics Seminar

Title: Ideals in enveloping algebras of affine Kac-Moody algebras
Speaker: Rekha Biswal (NISER, Bhubaneswar)
Date: 17 November 2023
Time: 11:30 am
Venue: LH-3, Mathematics Department

In this talk, I will discuss about the structure of ideals in enveloping algebras of affine Kac–Moody algebras and explain a proof of the result which states that if $U(L)$ is the enveloping algebra of the affine Lie algebra $L$ and “$c$” is the central element of $L$, then any proper quotient of $U(L)/(c)$ by two sided ideals has finite Gelfand–Kirillov dimension. I will also talk about the applications of the result including the fact that $U(L)/(c-\lambda)$ for non zero $\lambda$ is simple. This talk is based on joint work with Susan J. Sierra.
