Tīmeklis2024. gada 21. maijs · Rational curves on elliptic K3 surfaces. We prove that any non-isotrivial elliptic K3 surface over an algebraically closed field of arbitrary characteristic contains infinitely many rational curves. This result was previously known in characteristic zero due to the work of Bogomolov and Tschinkel. Tīmeklis2024. gada 2. jūl. · Curves on K3 surfaces.

Conjecturally, the Brauer–Manin obstruction to the Hasse principle for 0-cycles of degree 1 is the only one for smooth, proper, geometrically integral varieties over k (see [ 13] and [ 1 ]).

The answer is provided by the following Theorem 1.1. Suppose there exists a dominant rational map φ: A 99K S from a surface A with trivial canonical class to a K3 surface S. Suppose also that deg φ ≥ 2. Then the Picard number ρ(S) is ...
