Components of $V (ρ) \otimes V (ρ)$ and dominant weight polyhedra for affine Kac-Moody Lie algebras

Sam Jeralds, Shrawan Kumar

Kostant asked the following question: Let $g$ be a simple Lie algebra over the complex numbers. Let $λ$ be a dominant integral weight. Then, $V (λ)$ is a component of $V(…

Twisted conformal blocks and their dimension

Jiuzu Hong, Shrawan Kumar

Let $Γ$ be a finite group acting on a simple Lie algebra $g$ and acting on a $s$ -pointed projective curve $(Σ, p = {p_{1}, \dots, p_{s}})$ faithfully (for $s \geq 1$ ).…
