Formality for rigid-analytic spaces satisfying the weight-monodromy conjecture
Alexander Petrov, Bogdan Zavyalov
We prove that étale and de Rham cohomology algebras of a smooth proper rigid-analytic space over a finite extension of are formal if the rigid-analytic space satisfi…
Non-decomposability of the de Rham complex and non-semisimplicity of the Sen operator
Alexander Petrov
We describe the obstruction to decomposing in degrees the de Rham complex of a smooth variety over a perfect field of characteristic that lifts over , and…
Universality of the Galois action on the fundamental group of
Alexander Petrov
We prove that any semi-simple representation of the Galois group of a number field coming from geometry appears as a subquotient of the ring of regular functions on the pro-algebra…
Hodge numbers are not derived invariants in positive characteristic
Nicolas Addington, Daniel Bragg
We study a pair of Calabi-Yau threefolds X and M, fibered in non-principally polarized Abelian surfaces and their duals, and an equivalence D^b(X) = D^b(M), building on work of Gro…
Geometrically irreducible -adic local systems are de Rham up to a twist
Alexander Petrov
We prove that any geometrically irreducible -local system on a smooth algebraic variety over a -adic field becomes de Rham after a twist by a charac…
Rigid-analytic varieties with projective reduction violating Hodge symmetry
Alexander Petrov
We construct examples of smooth proper rigid-analytic varieties admitting formal model with projective special fiber and violating Hodge symmetry for cohomology in degrees …
On the periodic topological cyclic homology of DG categories in characteristic p
Alexander Petrov, Vadim Vologodsky
We prove that the -adically completed periodic topological cyclic homology of a DG category over a perfect field of characteristic is isomorphic to the (-adically c…
The Gauss-Manin connection on the periodic cyclic homology
Alexander Petrov, Dmitry Vaintrob, Vadim Vologodsky
It is expected that the periodic cyclic homology of a DG algebra over the field of complex numbers (and, more generally, the periodic cyclic homology of a DG category) carries a lo…
