Fargues's étale cohomology comparison conjecture for the Fargues–Fontaine curve
Fargues's étale cohomology comparison conjecture for the Fargues–Fontaine curve
Let be a -adic field, let be the coefficient field defining the Fargues–Fontaine curve, and let and denote its algebraic and adic versions. Let be the morphism of étale sites, and for a constructible -module on , write . Fargues's comparison conjecture. For every , there is an isomorphism
This conjecture predicts that algebraic and adic étale cohomology agree for arbitrary constructible torsion coefficients. The comparison is motivated by the known relationship between the étale cohomology of local systems on the curve and Galois cohomology, while its validity in all degrees for constructible sheaves remains open.
