Geometric invariant theory and stretched Kostka quasi-polynomials

Marc Besson, Sam Jeralds, Joshua Kiers

For $G$ a semisimple, simply-connected complex algebraic group and two dominant integral weights $λ, μ$ , we consider the dimensions of weight spaces $V_{λ} (μ)$ of weight $μ$ 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 $g$ with Cartan and Borel subalgebras $h \subset b \subset g$ , affine Demazure modules are…

Irreducible components in Hochschild cohomology of flag varieties

Sam Jeralds

Let $G$ be a simple, simply-connected complex algebraic group with Lie algebra $g$ , and $G / B$ the associated complete flag variety. The Hochschild cohomology $HH^\bullet…
