Crystals of relative displays and Calabi-Yau threefolds
Oliver Gregory
Displays can be thought of as relative versions of Fontaine's notion of strongly divisible lattice from integral -adic Hodge theory. In favourable circumstances, the crystalline…

Motivic cohomology and algebraic -theory of some surfaces over finite fields
Oliver Gregory
We compute the algebraic -theory of some classes of surfaces defined over finite fields. We achieve this by first calculating the motivic cohomology groups and then studying the…

p-adic Tate conjectures and abeloid varieties
Oliver Gregory, Christian Liedtke
We explore Tate-type conjectures over -adic fields. We study a conjecture of Raskind that predicts the surjectivity of $$ ({\rm NS}(X_{\bar{K}}) \otimes_{\mathbb{Z}}\mathbb{Q}_p…
