Flag Space, Matroidal Schur Algebras and the Steinberg Representation

Carl Mautner

We define via generators and relations an extended version of the matroidal Schur algebras introduced in earlier work of the author with Tom Braden. In the case of projective geome…

Perverse sheaves on symmetric products of the plane

Tom Braden, Carl Mautner

For any field $k$ , we give an algebraic description of the category $Perv_{S} (S^{n} (C^{2}), k)$ of perverse sheaves on the $n$ -fold symmetric product of the p…

An Intersection Matrix for Affine Hyperplane Arrangements

Jens Niklas Eberhardt, Carl Mautner

For a real affine hyperplane arrangement, we define an integer intersection matrix with a natural $q$ -deformation related to the intersections of bounded chambers of the arrangemen…
