SUMMARY:Workshop / Seminar:Commutative Algebra Seminar
DESCRIPTION:It is a classic result of Hochster and Huneke that (generic) determinantal rings over a perfect field of positive characteristic have F-regular singularities. But what about the singularities of determinantal pairs? A determinantal pair (R\,P) consists of a generic determinantal ring R and a standard height-1 prime ideal P generating the divisor class group of R (say\, if R is defined by t-minors then P is generated by the (t-1)-minors of the first t-1 rows of variables defining R). It is natural to ask whether determinantal pairs have purely F-regular singularities\, which is a generalized notion of F-regularity for pairs. In my talk\, I will present an answer to this question. This is joint work with Arnaud Vilpert. Speaker(s): Javier Carvajal-Rojas (EPFL (Ecole Polytechnique Federal de Lausanne))
