Stochastic six-vertex models, Hall-Littlewood positivity and $t$ -deformed Schensted insertions

Konstantin Matveev

We prove a positivity theorem for a certain family of operators defined in terms of the stochastic six-vertex model. We explore connections of this result with other vertex models…

Factorization of certain Macdonald Littlewood-Richardson coefficients

Konstantin Matveev, Yuchen Wei

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