WebCrystalline cohomology is a p-adic cohomology theory for smooth, proper varieties in characteristic p. Our goal will be to understand the construction and basic properties of crystalline cohomology. Topics will depend on interest but may include the de Rham - Witt complex, rigid comohology or the interaction of Frobenius and the Hodge filtration.

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 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 vectors of k (that gives back X on 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 … See more For a variety X over an algebraically closed field of characteristic p > 0, the $${\displaystyle \ell }$$-adic cohomology groups for $${\displaystyle \ell }$$ any prime number other than p give satisfactory cohomology groups of X, with coefficients in the ring See more In characteristic p the most obvious analogue of the crystalline site defined above in characteristic 0 does not work.

To add a bit more to Brian's comment: the crystalline cohomology of an abelian variety (over a finite field of characteristic p, say) is canonically isomorphic to the Dieudonné module of the p-divisible group of the abelian variety (which is a finite free module over the Witt vectors of the field with a semi-linear Frobenius). how big are electrons compared to protonsWebLuc Illusie1 1. Grothendieck at Pisa Grothendieck visited Pisa twice, in 1966, and in 1969.
