The big de Rham–Witt complex [PDF]

open access: yesActa Mathematica, 2015
This paper gives a new and direct construction of the multi-prime big de Rham-Witt complex which is defined for every commutative and unital ring; the original construction by the author and Madsen relied on the adjoint functor theorem and accordingly was very indirect.

Higher Displays Arising from Filtered de Rham–Witt Complexes [PDF]

open access: yesProgress in Mathematics, 2021
For a smooth projective scheme X over a ring R on which p is nilpotent that meets some general assumptions we prove that the crystalline cohomology is equipped with the structure of a higher display which is a relative version of Fontaine’s strongly divisible lattices.

Integral Monsky-Washnitzer cohomology and the overconvergent de Rham-Witt complex [PDF]

open access: yesMathematical Research Letters, 2014
In their paper which introduced Monsky-Washnitzer cohomology, Monsky and Washnitzer described conditions under which the definition can be adapted to give integral cohomology groups. It seems to be well-known among experts that their construction always gives well-defined integral cohomology groups, but this fact also does not appear to be explicitly ...

An analogue of the Milnor conjecture for the de Rham-Witt complex in characteristic 2

open access: yesForum of Mathematics, Sigma
We describe the modulo $2$ de Rham-Witt complex of a field of characteristic $2$ , in terms of the powers of the augmentation ideal of the $\mathbb {Z}/2$ -geometric fixed points of real topological restriction homology ${\mathrm ...

A motivic construction of the de Rham-Witt complex

open access: yesJournal of Pure and Applied Algebra
The theory of reciprocity sheaves due to Kahn-Saito-Yamazaki is a powerful framework to study invariants of smooth varieties via invariants of pairs $(X,D)$ of a variety $X$ and a divisor $D$. We develop a generalization of this theory where $D$ can be a $\mathbb{Q}$-divisor.

Revisiting the de Rham-Witt complex [PDF]

open access: yesAstérisque, 2021
The goal of this paper is to offer a new construction of the de Rham-Witt complex of smooth varieties over perfect fields of characteristic $p>0$. We introduce a category of cochain complexes equipped with an endomorphism $F$ of underlying graded abelian groups satisfying $dF = pFd$, whose homological algebra we study in detail.
