Hive-type polytopes for quiver multiplicities and the membership problem for quiver moment cones

Calin Chindris, Brett Collins, Daniel Kline

Let $Q$ be a bipartite quiver with vertex set $Q_{0}$ such that the number of arrows between any source vertex and any sink vertex is constant. Let $β = (β (x))_{x \in Q_{0}}$ be a dimens…

Generalized Littlewood-Richardson coefficients for branching rules of GL(n) and extremal weight crystals

Brett Collins

Following the methods used by Derksen-Weyman in \cite{DW11} and Chindris in \cite{Chi08}, we use quiver theory to represent the generalized Littlewood-Richardson coefficients for t…
