Integral p-adic cohomology theories for open and singular varieties

Veronika Ertl, Atsushi Shiho, Johannes Sprang

For open and singular varieties in positive characteristic p we study the existence of an integral p-adic cohomology theory which is finitely generated, compatible with log crystal…

Rigid analytic reconstruction of Hyodo--Kato theory

Veronika Ertl, Kazuki Yamada

We give a new and very intuitive construction of Hyodo--Kato cohomology and the Hyodo--Kato map, based on logarithmic rigid cohomology. We show that it is independent of the choice…

On infiniteness of integral overconvergent de Rham-Witt cohomology modulo torsion

Veronika Ertl, Atsushi Shiho

In this article, we give examples of smooth varieties of positive characteristic whose first integral overconvergent de Rham-Witt cohomology modulo torsion is not finitely generate…

A new proof of a vanishing result due to Berthelot, Esnault, and Rülling

Veronika Ertl

The goal of this small note is to give a more concise proof of a result due to Berthelot, Esnault, and Rülling. For a regular, proper, and flat scheme over a discrete valuation…

Comparison between rigid syntomic and crystalline syntomic cohomology for strictly semistable log schemes with boundary

Veronika Ertl, Kazuki Yamada

We introduce rigid syntomic cohomology for strictly semistable log schemes over a complete discrete valuation ring of mixed characteristic (0,p). In case a good compactification ex…

Full faithfulness for overconvergent F-de Rham-Witt connections

Veronika Ertl

Let X be a smooth variety over a perfect field of characteristic p>0. In this small note we define overconvergent F-de Rham-Witt connections as an analogue for F-crystals over prop…

Comparison between Rigid and Overconvergent Cohomology with Coefficients

Veronika Ertl

For a smooth scheme over a perfect field of characteristic p>0, we generalise a definition of Bloch and introduce overconvergent de Rham-Witt connections. This provides a tool to e…

Overconvergent Chern Classes and Higher Cycle Classes

Veronika Ertl

The goal of this work is to construct integral Chern classes and higher cycle classes for a smooth variety over a perfect field of characteristic p>0 that are compatible with the r…
