Overconvergent prismatic cohomology
Andreas Langer
In this note I define an overconvergent version of prisms and prismatic cohomology as introduced by Bhatt and Scholze and show that overconvergent prismatic cohomology specialises…
A log-motivic cohomology for semistable varieties and its -adic deformation theory
Oliver Gregory, Andreas Langer
We construct log-motivic cohomology groups for semistable varieties and study the -adic deformation theory of log-motivic cohomology classes. Our main result is the deformationa…
Hodge-Witt decomposition of relative crystalline cohomology
Oliver Gregory, Andreas Langer
For a smooth and proper scheme over an artinian local ring with ordinary reduction over the perfect residue field we prove - under some general assumptions - that the relative de R…
Overconvergent de Rham-Witt cohomology for semistable varieties
Oliver Gregory, Andreas Langer
We define an overconvergent version of the Hyodo-Kato complex for semistable varieties over perfect fields of positive characteristic, and prove that its hypercohomology tensor…
Higher displays arising from filtered de Rham-Witt complexes
Oliver Gregory, Andreas Langer
For a smooth projective scheme over a ring on which is nilpotent that meets some general assumptions we prove that the crystalline cohomology is equipped with the struc…
Overconvergent Witt Vectors
Christopher Davis, Andreas Langer, Thomas Zink
Let A be a finitely generated algebra over a field K of characteristic p >0. We introduce a subring of the ring of Witt vectors W(A). We call it the ring of overconvergent Witt vec…
