Let $G$ be a reductive group with Langlands dual group $G$, and let $kappa$ and $check\kappa$ be invariant forms on their Lie algebras such that, for the mutually dual Cartan subal…

Let $G_1$ be a simple group, let $G_1$ be its Langlands dual group, and let $kappa_1$ be the invariant form used to define the Kazhdan–Lusztig category $KL^{kappa_1}(G_1)$. Let…
