Cartier transform and prismatic crystals

Michel Gros, Bernard Le Stum and Adolfo Quirós

Vol. 5 (2023), No. 3, 405–456
Abstract

We show that the abstract equivalence of categories, called the Cartier transform, between crystals on the q-crystalline and prismatic sites can be locally identified with the explicit local q-twisted Simpson correspondence. This establishes four equivalences that are all compatible with the relevant cohomology theories. We restrict ourselves for simplicity to the one-dimensional case.
