Blow-up invariance for Hodge-Witt sheaves with modulus
Atsushi Shiho
In this paper, we prove the blow-up invariance for Hodge-Witt sheaves with modulus, which is a generalization of a result of Koizumi for Witt sheaves and that of Kelly-Miyazaki and…
Theory of weights for log convergent cohomologies I: the case of a proper smooth scheme with an SNCD in characteristic p>0
Yukiyoshi Nakkajima, Atsushi Shiho
Using log convergent topoi, %In the derived category of filtered complexes of %sheaves of modules over %an isostructure we define two fundamental filtered complexes …
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…
Comparison of relatively unipotent log de Rham fundamental groups
Bruno Chiarellotto, Valentina Di Proietto, Atsushi Shiho
In this paper, we prove compatibilities of various definitions of relatively unipotent log de Rham fundamental groups for certain proper log smooth integral morphisms of fine log s…
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…
On comparison between relative log de Rham-Witt cohomology and relative log crystalline cohomology
Kazuki Hirayama, Atsushi Shiho
In this article, we prove the comparison theorem between the relative log de Rham-Witt cohomology and the relative log crystalline cohomology for a log smooth saturated morphism of…
