In the present work, we are concerned only with equivalence ... 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.
