Littlewood--Richardson rules from quivers for two-step flag varieties

Linda Chen, Elana Kalashnikov, Appendix by Ellis Buckminster

Let ${\bigwedge }_1$ and ${\bigwedge }_2$ be two symmetric function algebras in independent sets of variables. We define vector space bases of $\bigwedge_1 \otimes_\mathbb{Z} \bigwedge_2…
