A homotopy exact sequence for overconvergent isocrystals
Christopher Lazda, Ambrus Pál
In this article we prove exactness of the homotopy sequence of overconvergent -adic fundamental groups for a smooth and projective morphism in characteristic . We do so by fi…

Cycle classes in overconvergent rigid cohomology and a semistable Lefschetz theorem
Christopher Lazda, Ambrus Pál
In this article we prove a semistable version of the variational Tate conjecture for divisors in crystalline cohomology, stating that a rational (logarithmic) line bundle on the sp…

A Néron-Ogg-Shafarevich criterion for K3 surfaces
Bruno Chiarellotto, Christopher Lazda, Christian Liedtke
The naive analogue of the Néron-Ogg-Shafarevich criterion is false for K3 surfaces, that is, there exist K3 surfaces over Henselian, discretely valued fields , with unramified $…
