Description:
Date and Time: Tuesday 28 July, 6:30 pm IST - 7:30 pm IST (joining time : 6:15 pm IST - 6:30 pm IST) Google Meet Link: https://meet.google.com/oku-xudb-imy Speaker: Melvin Hochster, University of Michigan. Title: Tight Closure, lim Cohen-Maculay sequences, content of local cohomology, and related open questions - Part 2. Abstract: The talks will give multiple characterizations of tight closure, discuss some of its applications, indicate connections with the existence of big and small Cohen-Macaulay algebras and modules, as well as variant notions, and also explain connections with the theory of content. There will be some discussion of the many open questions in the area, including the very long standing problem of proving that Serre intersection multiplicities have the behavior one expects.
