Crystalline cohomology
Webin crystalline cohomology: when de ning the crystalline cohomology of an a ne scheme, one may just work with the indiscrete topology on the crystalline site of the a ne (so all presheaves are sheaves) while still computing the correct crystalline cohomology groups.

Webthe prismatic cohomology of R(1); up to a Frobenius twist, this is analogous to computing the crystalline cohomology of a smooth Z p-algebra Ras the de Rham cohomology of a lift of Rto Z p. The following notation will be used throughout this lecture. Notation 0.1. We view A:= Z pJq 1K as as -ring via (q) = 0. Unless otherwise speci ed, the ring Z Webany p-torsion free crystal E ∈Crys(X/W). The proofs of Theorem 1.1 imply also the following variant for Chern classes in torsion crystalline cohomology: Let Wn:= W/pnW. Then, if X is as in Theorem 1.1 and if E is a locally free crystal on X/Wn, then c crys i (EX) is zero in the torsion crystalline cohomology group H2i crys(X/Wn) for i ≥1 ...
http://www-personal.umich.edu/~malloryd/haoyang.pdf WebCrystalline cohomology was invented by A.Grothendieck in 1966 to construct a Weil cohomology theory for a smooth proper variety X over a field k of characteristic p > 0. Crystals are certain sheaves on the crystalline site.
