Algebraic Frobenius Splitting of Cotangent Bundles of Flag Varieties
Chuck Hague
Following the program of algebraic Frobenius splitting begun by Kumar and Littelmann, we use representation-theoretic techniques to construct a Frobenius splitting of the cotangent…

Cohomology of Flag Varieties and the Brylinski-Kostant Filtration
Chuck Hague
Let G be a semisimple complex algebraic group with Borel subgroup B and let P be a parabolic subgroup of G. Let T*(G/P) denote the cotangent bundle of G/P. Ranee Brylinski discover…
