WebCrystalline cohomology is a p-adic cohomology theory for varieties in characteristicp created by Berthelot [Ber74]. It was designed to fill the gap at p left by the discovery [SGA73] of ℓ-adic cohomology forℓ 6= p. The construction of crystalline cohomology relies on the crystalline site, which is a better behaved positive characteristic ... WebGrothendieck visited Pisa twice, in 1966, and in 1969. It is on these occasions that he conceived his theory of crystalline cohomology and wrote foundations for the theory of deformations of p -divisible groups, which he called Barsotti-Tate groups. He did this in two letters, one to Tate, dated May 1966, and one to me, dated Dec. 2–4, 1969.

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.
