Derived Enhancements of -fixed subschemes
Marc Besson, Shiyixin Liang
For a conical affine symplectic singularity with -action, the fixed scheme and the map carry much information about…
Tangent spaces of spherical Schubert varieties and counterexamples to the reducedness conjecture
Marc Besson, Jiuzu Hong, Huanhuan Yu
Given a simply-connected simple algebraic group , we determine the tangent space of any Finkelberg-Mirković Schubert scheme at the base point of the affine Grassmannian of .…
Reduction rules for Demazure modules
Marc Besson, Sam Jeralds, Joshua Kiers
For a complex reductive group and a Borel subgroup, we provide a reduction rule for certain weight multiplicities in Demazure modules : given a weight $μ…
Geometric invariant theory and stretched Kostka quasi-polynomials
Marc Besson, Sam Jeralds, Joshua Kiers
For a semisimple, simply-connected complex algebraic group and two dominant integral weights , we consider the dimensions of weight spaces of weight in the i…
Affine Demazure Weight Polytopes and Twisted Bruhat Orders
Marc Besson, Sam Jeralds, Joshua Kiers
For an untwisted affine Kac-Moody Lie algebra with Cartan and Borel subalgebras , affine Demazure modules are…
Weight polytopes and saturation of Demazure characters
Marc Besson, Sam Jeralds, Joshua Kiers
For a reductive group and a maximal torus and Borel subgroup, Demazure modules are certain -submodules, indexed by elements of the Weyl group, of the finite irr…
