10:00 - 11:00 AM
Cohomological and homogeneity conditions on the Jacobian of a polynomial
Speaker: Uli Walther
Abstract: The free resolution of the Jacobian ideal of a polynomial contains a lot of geometric information on the hypersurface. "Freeness" arises if the resolution is as short as it can be (barring smoothness). We discuss natural sources, weakenings, and implications of freeness under varying homogeneity conditions.

11:30 AM - 12:30 PM
Associated primes of local cohomology modules
Speaker: Gennady Lyubeznik
Abstract: : I will give a survey of work on associated primes of local cohomology modules, including the very latest results.

2:00 - 3:00 PM
Regularity of group cohomology
Speaker: Peter Symonds
Abstract: We will survey what is known about local cohomology and regularity of cohomology rings of groups and invariants.
