Algebra and Algebraic Geometry Seminar - Graham Keiper - Regularity and h-Polynomials of Toric Ideals of Graphs
Title: Regularity and h-Polynomials of Toric Ideals of GraphsSpeaker: Graham Keiper (McMaster University)
Abstract: I will discuss recent work of Favacchio, Van Tuyl and myself which demonstrates that we may construct toric ideals associated with graphs which have regularity r and h-polynomials of degree d for any 4 \leq r\leq d. The ideas involved rely on Gröbner bases and combinatorics. I will also discuss how we can use this to recover a result of Hibi, Higashitani, Kimura, and O’Keefe.
