Langlands program for pp-adic coefficients

About 15 years old · traced to

Let pp be a prime, let kk be a finite field with q=psq=p^s elements, and let XX be a smooth proper geometrically connected curve over Spec⁡(k)\operatorname{Spec}(k) with function field K\mathcal{K}. Let Ar\mathcal{A}_r be the set of isomorphism classes of irreducible cuspidal automorphic representations of GL⁡r(AK)\operatorname{GL}_r(\mathbb{A}_{\mathcal{K}}) with finite-order central character. Let Ir\mathcal{I}_r be the direct limit, over dense open subschemes U⊂XU\subset X and finite extensions of K0=W(k)⊗QK_0=W(k)\otimes\mathbb{Q} in Q‾p\overline{\mathbb{Q}}_p, of the isomorphism classes of absolutely irreducible overconvergent FF-isocrystals of rank rr with finite determinant. For an object, write UU for the common set of unramified places, and compare Frobenius eigenvalues with Hecke eigenvalues at x∈∣U∣x\in|U|. Langlands program for pp-adic coefficients. There are unique maps

π∙ ⁣:Ir→Ar,E∙ ⁣:Ar→Ir\pi_{\bullet}\colon\mathcal{I}_r\rightarrow\mathcal{A}_r,\qquad E_{\bullet}\colon\mathcal{A}_r\rightarrow\mathcal{I}_r

such that, for every E∈IrE\in\mathcal{I}_r, the Frobenius eigenvalues of EE at every x∈∣U∣x\in|U| coincide with the Hecke eigenvalues of πE\pi_E, and, for every π∈Ar\pi\in\mathcal{A}_r, the Frobenius eigenvalues of EπE_\pi at every x∈∣U∣x\in|U| coincide with the Hecke eigenvalues of π\pi. Moreover,

E∙∘π∙=id⁡I,π∙∘E∙=id⁡A.E_{\bullet}\circ\pi_{\bullet}=\operatorname{id}_{\mathcal{I}},\qquad \pi_{\bullet}\circ E_{\bullet}=\operatorname{id}_{\mathcal{A}}.

This is the proposed pp-adic-coefficient form of the Langlands correspondence for curves, matching unramified local data in both directions. The supplied text gives no resolution, so the conjecture is recorded as open.
