$\infty$-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 -adic Hodge theory in this setting over small -stacks after Scholze and we also consider certain moduli -stack which parametrizes families of mixed-parity Hodge modules. Examples of the small -stacks in our mind are rigid analytic spaces over -adic fields and moduli -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 -category over related to smooth representations of reductive groups, while the other side of the generalized Langlands correspondence in the geometric setting is the corresponding derived -category over the stack of mixed-parity -parametrizations (i.e. from two-fold covering of the Weil group into -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 -adic cohomologicalization to immediately achieve various solid derived -categories , , and so on with well-established formalism regarding 6-functors, we already provide certain -adic cohomologicalization of the story over .
