Student Commutative Algebra Date:  Wednesday, January 23, 2013 Location:  2866 East Hall (3:00 PM to 4:00 PM) Title:  An overview of tight closure Abstract:   Tight closure is an operation on ideal in ring of prime characteristic. Since this theory was introduced by Hochster and Huneke in the 80s, it has been used to study several properties of a ring, for instance, Cohen-Macaulayness. In the last years it has been used to study singularity through test ideals and several invariants. In this talk we will give a general picture of this beautiful theory and its applications.
