The logarithmic Riemann–Hilbert correspondence conjecture for geometric local systems

About 8 years old · traced to

Let XX be a smooth algebraic variety over a number field EE. Fix an isomorphism ι:Q‾p→∼C\iota:\overline{\mathbb{Q}}_p\stackrel{\sim}{\to}\mathbb{C} and a field homomorphism σ:E→C\sigma:E\to\mathbb{C}, and write σX=X⊗E,σC\sigma X=X\otimes_{E,\sigma}\mathbb{C}. Let vv be the pp-adic place of EE induced by E→σC→ι−1Q‾pE\xrightarrow{\sigma}\mathbb{C}\xrightarrow{\iota^{-1}}\overline{\mathbb{Q}}_p, and let EvE_v be the corresponding completion. A pp-adic étale local system L\mathbb{L} on XX is geometric if every stalk at a geometric point over a closed point gives a geometric pp-adic representation in the sense of Fontaine–Mazur. For geometric L\mathbb{L}, the de Rham construction gives a regular integrable connection DdRalg(L∣XEv)⊗Ev,ιCD_{\mathrm{dR}}^{\mathrm{alg}}(\mathbb{L}|_{X_{E_v}})\otimes_{E_v,\iota}\mathbb{C} on σX\sigma X, equipped with its decreasing filtration Fil∙\mathrm{Fil}^{\bullet}, while the classical Riemann–Hilbert construction gives a regular integrable connection from the associated complex local system.

Logarithmic Riemann–Hilbert correspondence conjecture. The two tensor functors from the category of geometric pp-adic étale local systems on XX to the category of regular integrable connections on σX\sigma X are canonically isomorphic. Moreover,

(DdRalg(L∣XEv)⊗Ev,ιC,Fil∙)\bigl(D_{\mathrm{dR}}^{\mathrm{alg}}(\mathbb{L}|_{X_{E_v}})\otimes_{E_v,\iota}\mathbb{C},\mathrm{Fil}^{\bullet}\bigr)

is a complex variation of Hodge structures.

This predicts compatibility between the classical and pp-adic de Rham realizations of geometric local systems, including the Hodge-theoretic structure carried by the de Rham realization. The supplied text does not state whether the claim has been proved or remains open.
