Webcohomology of a prismatic crystal is a perfect complex of A-modules with tor-amplitude in degrees [0,2n]. We also establish a Poincar´e duality for the reduced prismatic crystals, i.e. the crystals over the reduced structural sheaf of (X/A)∆. The key ingredient is an explicit local description of reduced prismatic crystals in terms of Higgs ... In mathematics, crystalline cohomology is a Weil cohomology theory for schemes X over a base field k. Its values H (X/W) are modules over the ring W of Witt vectors over k. It was introduced by Alexander Grothendieck (1966, 1968) and developed by Pierre Berthelot (1974). Crystalline cohomology is partly inspired … See more For schemes in characteristic p, crystalline cohomology theory can handle questions about p-torsion in cohomology groups better than p-adic étale cohomology. This makes it a natural backdrop for much of the work on See more In characteristic p the most obvious analogue of the crystalline site defined above in characteristic 0 does not work. The reason is roughly that in order to prove exactness of the de Rham complex, one needs some sort of Poincaré lemma, whose proof in turn … See more • Motivic cohomology • De Rham cohomology See more For a variety X over an algebraically closed field of characteristic p > 0, the $${\displaystyle \ell }$$-adic cohomology groups for See more One idea for defining a Weil cohomology theory of a variety X over a field k of characteristic p is to 'lift' it to a variety X* over the ring of Witt … See more If X is a scheme over S then the sheaf OX/S is defined by OX/S(T) = coordinate ring of T, where we write T as an abbreviation for an object U → T of Cris(X/S).
