All linear symmetries of the $SU (3)$ tensor multiplicities

Emmanuel Briand, Mercedes Rosas, Stefan Trandafir

The $SU (3)$ tensor multiplicities are piecewise polynomial of degree $1$ in their labels. The pieces are the chambers of a complex of cones. We describe in detail this cha…

A comment of the combinatorics of the vertex operator $Γ_{(t ∣ X)}$

Mercedes Helena Rosas

The Jacobi--Trudi identity associates a symmetric function to any integer sequence. Let $Γ_{(t ∣ X)}$ be the vertex operator defined by $Γ_{(t|X)} s_α=\sum_{n \in \mathbb{Z}} s_{(n,α…
