Tīmeklis1997. gada 30. janv. · Counting rational curves on K3 surfaces. Arnaud Beauville. The aim of these notes is to explain the remarkable formula found by Yau and Zaslow to express the number of rational curves on a K3 surface. Projective K3 surfaces fall into countably many families F (g) (g>0); a surface in F (g) admits a g-dimensional linear …
Tīmeklistrivial canonical class to a given K3 surface constrainthis K3 surface from being “general enough”? 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 ...
Tīmeklis2013. gada 20. apr. · We show that supersingular K3 surfaces in characteristic $$p\ge 5$$p≥5 are related by purely inseparable isogenies. This implies that they are unirational, which proves conjectures of Artin, Rudakov, Shafarevich, and Shioda.
