WebAug 1, 2024 · For varieties over a perfect field of characteristic p, étale cohomology with Q ℓ-coefficients is a Weil cohomology theory only when ℓ ≠ p; the corresponding role for ℓ = p is played by Berthelot's rigid cohomology. In that theory, the coefficient objects analogous to lisse ℓ-adic sheaves are the overconvergent F-isocrystals.This expository article is a … WebCrystalline cohomology is known to be a goodp-adic cohomology theory for a scheme which is proper and smooth overk, but it does not work well for a non-proper scheme. Here we takeHi c as (compactly supported) rigid cohomology introduced by Berthelot ([Be1]). Let us recall it brie・Z.
