WebPrismatic cohomology is a recently developed cohomology theory for schemes over p-adic rings. It is related to both (p-adic) etale and de Rham/crystalline cohomology, and so also to p-adic Hodge theory. It relates to aspects of p-adic Hodge theory that previously had not seemed to be of a cohomological nature --- for example, Breuil--Kisin ...

A mini-course on crystalline cohomology

WebWe wish to construct a complex computing crystalline cohomology. To begin with, we note that there’s no functor that does: R 7! b Re=W where R is a at lift of R to W. The following deformation theory result says that we can nde at least one lift, but they are most de nitely not unique.

WebIn Section 2, the pro-unipotent crystalline fundamental group is deﬁned, together with a cosimplicial algebra which can be thought of as the crystalline homotopy type. The cohomology groups of the crystalline homotopy type are the crystalline cohomology groups of the scheme, and the pro-unipotent fundamental group can be recovered from the ...

Web1960s Grothendieck deﬁned etale cohomology and crystalline cohomology, and showed that´ the algebraically deﬁned de Rham cohomology has good properties in characteristic zero. The problem then became that we had too many good cohomology theories!
