Algebra and Algebraic Geometry Seminar - Claudia Miller - Torsion in exterior powers of differentials over complete intersection rings

Description

Speaker: Claudia Miller (University of Syracuse)

Title: Torsion in exterior powers of differentials over complete intersection rings

Abstract: In this talk, after a review of the definition of and facts about Kaehler differentials, I will give some history behind the classic Lipman-Zariski Conjecture and the generalized Lipman-Zariski questions of Graf. Then I’ll give some results on the torsion and cotorsion of exterior powers of the module of Kaehler differentials over complete intersection rings, and say how these are used to prove a generalized Lipman-Zariski result under certain conditions. This is joint work with Sophia Vassiliadou.
