Strongly dominant weight polytopes are cubes

Gaston Burrull, Tao Gui, Hongsheng Hu

For any root system of rank $r$ , we study the "dominant weight polytope" $P^{λ}$ associated with a strongly dominant weight $λ$ . We prove that $P^{λ}$ is combinatorially equivalent to…

$p$ -Jones-Wenzl idempotents

Gaston Burrull, Nicolas Libedinsky, Paolo Sentinelli

For a prime number $p$ and any natural number $n$ we introduce, by giving an explicit recursive formula, the $p$ -Jones-Wenzl projector $^{p} JW_{n}$ , an element of the…
