Topos cohomology
WebThis book makes a systematic study of the relations between the étale cohomology of a scheme and the orderings of its residue fields. A major result is that in high degrees, étale cohomology is cohomology of the real spectrum. It also contains new contributions in group cohomology and in topos theory. WebJan 24, 2024 · In one sense, the answer is yes – you can certainly define cohomology and homotopy groups and so on for pretoposes and have them coincide with the classical definitions for Grothendieck toposes – but in another sense the answer is no – because you are essentially just embedding the pretopos into a suitable Grothendieck topos and …

WebOct 13, 2024 · Addendum : Morally, the use of higher topos theory in DCCT is as a generalization of the nonabelian cohomology of Grothendieck and Giraud. In DCCT, these generalized cohomology classes are given by higher principal bundles. Webcohomology is torsion free and the Hodge spectral sequence of X k degenerates at E 1, then these ‘‘Frobenius’’ Hodge numbers coincide with the ‘‘geometric’’ Hodge numbers: hi, j(8)=hi, j(X k) :=dim H j(X, 0i X k). (0.0.1) In fact, Mazur’s result is more precise. When the crystalline cohomology is torsion free, the De Rham ...
WebThis site then has good cohomological behaviour (e.g. if X is liftable to char. 0, then cohomology computed with the crystalline topos is what it "should be"). The theory of the crystalline topos was of course worked out very successfully by Pierre Berthelot. WebThe intrinsic cohomology of such \mathbf {H} is a nonabelian sheaf cohomology. The following discusses two such choices for \mathbf {H} such that the corresponding nonabelian sheaf cohomology coincides with H (X,A) (for paracompact X ). Petit (\infty,1) -sheaf (\infty,1) -topos

WebPrismatic cohomology is a recently developed cohomology theory for schemes over p-adic rings. It is related to both (p-adic) etale and de Rham/crystalline cohomology, and so also to p-adic Hodge theory.
