Quadratic Chabauty and rational points II: Generalised height functions on Selmer varieties

JS Balakrishnan, N Dogra - International Mathematics Research …, 2021 - academic.oup.com
We give new instances where Chabauty–Kim sets can be proved to be finite, by developing
a notion of “generalised height functions” on Selmer varieties. We also explain how to …

Good reduction criterion for K3 surfaces

Y Matsumoto - Mathematische Zeitschrift, 2015 - Springer
We prove a Néron–Ogg–Shafarevich type criterion for good reduction of K3 surfaces, which
states that a K3 surface over a complete discrete valuation field has potential good reduction …

On -adic absolute Hodge cohomology and syntomic coefficients. I

F Déglise, W Nizioł - Commentarii Mathematici Helvetici, 2018 - ems.press
We interpret syntomic cohomology defined in [50] as a p-adic absolute Hodge cohomology.
This is analogous to the interpretation of Deligne–Beilinson cohomology as an absolute …

A Néron–Ogg–Shafarevich criterion for K3 surfaces

B Chiarellotto, C Lazda… - Proceedings of the London …, 2019 - Wiley Online Library
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 K, with unramified ℓ‐adic …

Y Hoshi - J. Math. Sci. Univ. Tokyo, 2018 - repository.dl.itc.u-tokyo.ac.jp
In the present paper, we study the geometry of the stable models of proper hyperbolic curves
over p-adic local fields via the study of the geometrically pro-p étale fundamental groups of …

Semisimplicity of the Frobenius Action on π1

LA Betts, D Litt - Simons Symposium on P-adic Hodge Theory, 2019 - Springer
Let K be a finite extension of Qp with residue field of size q, and fix a prime l= p. Fix a choice
of geometric Frobenius ϕK∈ GK and an element σ∈ IK of inertia which generates tame …
