Two coniveau filtrations and algebraic equivalence over finite fields

Federico Scavia, Fumiaki Suzuki

We extend the basic theory of the coniveau and strong coniveau filtrations to the -adic setting. By adapting the examples of Benoist--Ottem to the -adic context, we sho…

Non-injectivity of the cycle class map in continuous -adic cohomology

Federico Scavia, Fumiaki Suzuki

Jannsen asked whether the rational cycle class map in continuous -adic cohomology is injective, in every codimension for all smooth projective varieties over a field of finit…

Non-algebraic geometrically trivial cohomology classes over finite fields

Federico Scavia, Fumiaki Suzuki

We give the first examples of smooth projective varieties over a finite field admitting a non-algebraic torsion -adic cohomology class of degree which va…

Higher-dimensional Calabi-Yau varieties with dense sets of rational points

Fumiaki Suzuki

We construct higher-dimensional Calabi-Yau varieties defined over a given number field with Zariski dense sets of rational points. We give two elementary constructions in arbitrary…

Factorization of the Abel-Jacobi maps

Fumiaki Suzuki

As an application of the theory of Lawson homology and morphic cohomology, Walker proved that the Abel-Jacobi map factors through another regular homomorphism. In this note, we giv…

A pencil of Enriques surfaces with non-algebraic integral Hodge classes

John Christian Ottem, Fumiaki Suzuki

We prove that there exists a pencil of Enriques surfaces defined over with non-algebraic integral Hodge classes of non-torsion type. This gives the first example of a…
