Commutative Algebra and its Interactions A conference in honor of Mel Hochster July 31 - August 5, 2008 Abstract Detail   Title: A geometric characterization of F-ideals/centers of F-purity In this talk we will discuss a positive characteristic analogue of centers of log canonicity (a notion from algebraic geometry). We will explore the structure of these objects in the F-pure setting. We will also link this notion to F-ideals, which are annihilators of Frobenius stable submodules of the top local cohomology (and to generalizations of such objects as studied by Lyubeznik and Smith).
