All first-year Science courses will be delivered virtually for Winter 2021. Due to the COVID-19 provincial lock-down, all students who were expecting in-person labs, should check their McMaster e-mail for important winter announcements..

Algebra and Algebraic Geometry - Jenna Rajchgot - Geometric vertex decomposition and liaison

Description

Title: Geometric vertex decomposition and liaison

Speaker: Jenna Rajchgot (McMaster University)

Abstract: Geometric vertex decomposition (a degeneration technique) and liaison are two frameworks that have been used to produce similar results about similar families of algebraic varieties. In this talk, I will review these two techniques and explain why they are useful for studying certain types of questions in algebraic geometry and commutative algebra. I will then discuss recent joint work with Patricia Klein on an explicit connection between geometric vertex decomposition and liaison, as well as applications of this connection.
