The induced PBW filtration, Frobenius splitting of double flag varieties, and Wahl's conjecture
Chuck Hague
Let G be a semisimple algebraic group over an algebraically closed field of positive characteristic p. Generalizing the construction of the PBW filtration on Weyl modules for G we…
Degenerate coordinate rings of flag varieties and Frobenius splitting
Chuck Hague
Recently E. Feigin introduced the -degenerations of semisimple algebraic groups and their associated degenerate flag varieties. It has been shown by Feigin, Finkelbe…
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…
Some Good-Filtration Subgroups of Simple Algebraic Groups
Chuck Hague, George McNinch
Let G be a connected and reductive algebraic group over an algebraically closed field of characteristic p > 0. An interesting class of representations of G consists of those G-modu…
On the B-canonical splittings of flag varieties
Chuck Hague
Let G be a semisimple algebraic group over an algebraically closed field of positive characteristic. In this note, we show that an irreducible closed subvariety of the flag variety…
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…
