Absolute calculus and prismatic crystals on cyclotomic rings

Michel Gros, Bernard Le Stum, Adolfo Quirós

Let be a prime, the ring of Witt vectors of a perfect field of characteristic and a primitive th root of unity. We introduce a new notion of calculus over $W…

Cartier transform and prismatic crystals

Michel Gros, Bernard Le Stum, Adolfo Quirós

We show that the abstract equivalence of categories, called Cartier transform, between crystals on the q-crystalline and prismatic sites can be locally identified with the explicit…

Twisted differential operators and -crystals

Michel Gros, Bernard Le Stum, Adolfo Quirós

We discuss the notion of a q-PD-envelope considered by Bhatt and Scholze in their recent theory of q-crystalline cohomology and explain the relation with our notion of a divided po…

Twisted calculus on affinoid algebras

Bernard Le Stum, Adolfo Quirós

We introduce the notion of a twisted differential operator of given radius relative to an endomorphism of an affinoid algebra A. We show that this notion is essentially indep…

Rigid cohomology of locally noetherian schemes Part 1 : Geometry

Bernard Le Stum

We set up the geometric background necessary to extend rigid cohomology from the case of algebraic varieties to the case of general locally noetherian formal schemes. In particular…

Constructible isocrystals

Bernard Le Stum

We introduce a new category of coefficients for p-adic cohomology called constructible isocrystals. Conjecturally, the category of constructible isocrystals endowed with a Frobeniu…
