Algebra and Algebraic Geometry - Jenna Rajchgot - 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.
