Commutative Algebra and its Interactions A conference in honor of Mel Hochster July 31 - August 5, 2008 Abstract Detail   Title: Rings of invariants A large part of Hochster's work in the 70s was devoted to proving the Cohen-Macaulay property for rings of invariants of linearly reductive groups. After several special cases (determinantal rings, Grassmannians, torus invariants) had been completed, the general case was settled by the Hochster-Roberts theorem. It uses reduction to characteristic p, another leitmotif in Hochster's work that has found its strongest expression in tight closure theory. We will survey Hochster's work and relate it to newer developments.
