All courses for every first-year Science student will be delivered online this fall. A limited number of students in their second, third and fourth years will return to campus for part of the semester.

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.
