Local cohomology with support in Schubert varieties

Michael Perlman

This paper is concerned with local cohomology sheaves on generalized flag varieties supported in closed Schubert varieties, which carry natural structures as (mixed Hodge) D-module…

Ideals preserved by linear changes of coordinates in positive characteristic

Bjørn Cattell-Ravdal, Erin Delargy, Akash Ganguly +4

We consider the polynomial ring in finitely many variables over an algebraically closed field of positive characteristic, and initiate the systematic study of ideals preserved by t…
