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.
