Let $G$ be a quasi-split reductive group over $E$, let $\check{G}$ be its Langlands dual group, and assume $\ell\nmid\lvert\pi_0(Z(G))\rvert$. Let $W_E$ be the Weil group and let…

Let $G$ be a quasi-split reductive group over $E$, let $\operatorname{Bun}_G$ be its moduli stack of $G$-bundles, and let $\operatorname{Bun}_G^b$ denote the stratum indexed by…

Fix a quasi-split reductive group $G$ over a local field $E$, and let $W_E$ be its Weil group. Let $\check{G}$ be the Langlands dual group, and let…
