There is no Definable Grauert Direct Image Theorem

Hélène Esnault, Moritz Kerz

We prove the claim in the title by showing that a definable Grauert Direct Image Theorem in o-minimal geometry would imply a weak representability-like property of the definable Pi…

Algebraic flat connections and o-minimality

Hélène Esnault, Moritz Kerz

We prove that an algebraic flat connection has definable flat sections in the analytic exponential structure if and only if it is regular singular with unitary monodromy eigenvalue…

A non-abelian version of Deligne's Fixed Part Theorem

Hélène Esnault, Moritz Kerz

We formulate and prove a non-abelian analog of Deligne's Fixed Part theorem on Hodge classes, revisiting previous work of Jost--Zuo, Katzarkov--Pantev and Landesman--Litt. To this…

A remark on crystalline cohomology

Moritz Kerz, Georg Tamme

We propose a new approach to crystalline cohomology based on the observation that one can lift smooth algebras uniquely "up to coherent homotopy."

Semistable Lefschetz Pencils

Hélène Esnault, Moritz Kerz

We study the geometry and cohomology of Lefschetz pencils for semistable schemes over a discrete valuation ring. We relate the global cohomological properties of the Lefschetz penc…

K-theory of non-archimedean rings II

Moritz Kerz, Shuji Saito, Georg Tamme

We study fundamental properties of analytic -theory of Tate rings such as homotopy invariance, Bass fundamental theorem, Milnor excision, and descent for admissible coverings.
