Factorization of certain Macdonald Littlewood-Richardson coefficients

Konstantin Matveev, Yuchen Wei

We find and prove a factorization formula for certain Macdonald Littlewood-Richardson coefficients $c_{\lambda \mu }^{\nu }(q,t)$. Namely, we consider the case that the Kostka number $K_{\mu ,\nu -\lambda }$…
