Title:On Lech's conjecture
Seminar:Algebra and Number Theory Seminar
Speaker:Linquan Ma, University of Michigan
Abstract:
I will talk about the long-standing conjecture of Lech on the multiplicities of a faithfully flat extension of local rings. I will start with some historical results and several attempts to attack this conjecture. And I will show how this conjecture is related to some questions on modules of finite length and projective dimension and discuss some recent progress.
