چکیده

We construct here many families of K3 surfaces that one can obtain as quotients algebraic by some subgroups the rank four complex reflection groups. find in total 15 with at worst $ADE$--singularities. In particular we classify all be obtained derived subgroup previous prove our results using geometry weighted projective spaces where these are embedded and theory Springer Lehrer-Springer on properties This construction generalizes a W.

Tate-Shafarevich groups and K3 surfaces

This paper explores a topic taken up recently by Logan and van Luijk, finding nontrivial 2-torsion elements of the Tate-Shafarevich group of the Jacobian of a genus-2 curve by exhibiting Brauer-Manin obstructions to rational points on certain quotients of principal homogeneous spaces of the Jacobian, whose desingularizations are explicit K3 surfaces. The main difference between the methods used...

Self-correspondences of K3 surfaces via moduli of sheaves and arithmetic hyperbolic reflection groups

An integral hyperbolic lattice is called reflective if its automorphism group is generated by reflections, up to finite index. Since 1981, it is known that their number is essentially finite. We show that K3 surfaces X over C with reflective Picard lattices can be characterized in terms of compositions of their self-correspondences via moduli of sheaves with primitive isotropic Mukai vector: Th...

K3 Surfaces with Interesting Groups of Automorphisms

By the fundamental result of I.I. Piatetsky-Shapiro and I.R. Shafarevich (1971), the automorphism group Aut(X) of a K3 surface X over C and its action on the Picard lattice SX are prescribed by the Picard lattice SX . We use this result and our method (1980) to show finiteness of the set of Picard lattices SX of rank ≥ 3 such that the automorphism group Aut(X) of the K3 surface X has a non-triv...

Classification of Extremal Elliptic K3 Surfaces and Fundamental Groups of Open K3 Surfaces

We present a complete list of extremal elliptic K3 surfaces (Theorem 1.1). As an application, we give a sufficient condition for the topological fundamental group of complement to an ADE-configuration of smooth rational curves on a K3 surface to be trivial (Proposition 4.1 and Theorem 4.3).

Global Torelli for Complex K3 Surfaces

Overview of statement and proof of Global Torelli, following Verbitsky. With an emphasis on a strong form of the theorem, giving a complete description of the category of complex K3s (and iso’s). 1. Motivation: classification of complex tori 2. Kähler classes and Weyl chambers Theorem 1. Let X be a complex K3. Let ω be a Kähler form on X. Then [ω] ∈ H(X,R) satisfies (1) [ω] ∈ H(X) (2) [ω] > 0 (...
