$\infty$-Categorical Generalized Langlands Program I: Mixed-Parity Modules and Sheaves

Abstract: Mixed-parity module emerges for instance when a de Rham Galois representation is being tensored with a square root of cyclotomic character, which produces half odd integers as the corresponding Hodge-Tate weights. We build the whole foundation on the $p$-adic Hodge theory in this setting over small $v$-stacks after Scholze and we also consider certain moduli $v$-stack which parametrizes families of mixed-parity Hodge modules. Examples of the small $v$-stacks in our mind are rigid analytic spaces over $p$-adic fields and moduli $v$-stack of vector bundles over Fargues-Fontaine curves. The preparation implemented at this level will be expected to provide further essential foundationalization for generalized Langlands program after Langlands, Drinfeld, Fargues-Scholze. One side of the generalized Langlands correspondence in the geometric setting is the perverse motivic derived $\infty$-category over $\mathrm{Moduli}G$ related to smooth representations of reductive groups, while the other side of the generalized Langlands correspondence in the geometric setting is the corresponding derived $\infty$-category over the stack of mixed-parity $L$-parametrizations (i.e. from two-fold covering of the Weil group into $\ell$-adic groups) related to the representations of Weil group in our setting into Langlands dual groups. Although after Scholze and Fargues-Scholze our generalized Langlands program can go along $\ell$-adic cohomologicalization to immediately achieve various solid derived $\infty$-categories $\mathrm{DerCat}\text{\'et}(\mathrm{Moduli}G,\square)$, $\mathrm{DerCat}\mathrm{lisse, \blacksquare}(\mathrm{Moduli}G,\square)$, $\mathrm{DerCat}{\blacksquare}(\mathrm{Moduli}_G,\square)$ and so on with well-established formalism regarding 6-functors, we already provide certain $p$-adic cohomologicalization of the story over $\mathrm{Moduli}_G$.
