Let $lambda\rightarrow\Lambda^+(n,d)$ be dominant, let $mathcal V_{\lambda}$ be the categorical module associated with $lambda$, and let $dot{\mathcal V}_{\lambda}$ be its Karoubi…

Let $lambda\rightarrow\Lambda^+(n,d)$ be a dominant weight, let $V_{\lambda}$ be the corresponding irreducible representation, and let $mathcal S(n,d)$ be the diagrammatic q-Schur…

For $n=d$, Williamson defines a nondegenerate $mathbbm Q$-semilinear form on the relevant categorified Schur algebra, while the source constructs a semilinear form on…

Let $lambda\rightarrow\ru(n,d)$ be a weight and let $mathbf i$ and $mathbf j$ be sequences for which the displayed 1-morphisms are defined. The morphism space is…

Let $lambda\rightarrow\ru(n,d)$ be arbitrary, and let $mu\rightarrow\ru(n,d)$ be obtained from $lambda$ by moving all zero entries to the end while preserving the relative order of…
