The saturation property for refined Littlewood-Richardson coefficients

Mrigendra Singh Kushwaha, K. N. Raghavan, Sankaran Viswanath

Given dominant integral weights $\hat{I}»,\hat{I}¼,\hat{I}½$ of a finite-dimensional simple Lie algebra $\mathfrak{g}$ and an element $w$ of its Weyl group, the refined tensor product multiplicity…
