Kummer rigidity for K3 surface automorphisms via Ricci-flat metrics
نویسندگان
چکیده
We give an alternative proof of a result Cantat \& Dupont, showing that any automorphism K3 surface with measure maximal entropy in the Lebesgue class must be Kummer example. Our method exploits existence Ricci-flat metrics on K3s and also covers non-projective case.

Marked length spectral rigidity for flat metrics
In this paper we prove that the space of flat metrics (nonpositively curved Euclidean cone metrics) on a closed, oriented surface is marked length spectrally rigid. In other words, two flat metrics assigning the same lengths to all closed curves differ by an isometry isotopic to the identity. The novel proof suggests a stronger rigidity conjecture for this class of metrics.
متن کاملNumerical Ricci - flat metrics on K 3
We develop numerical algorithms for solving the Einstein equation on Calabi-Yau manifolds at arbitrary values of their complex structure and Kähler parameters. We show that Kähler geometry can be exploited for significant gains in computational efficiency. As a proof of principle, we apply our methods to a one-parameter family of K3 surfaces constructed as blow-ups of the T /Z2 orbifold with ma...
متن کاملA Rigidity Theorem for Affine Kähler-Ricci Flat Graph
where (U ) is the cofactor matrix of the Hessian matrix Df of a smooth convex function f defined in a convex domain Ω ⊂ R. The PDE (1.2) is the equation for affine maximal hypersurfaces. Obviously, every solution of (1.1) is a solution of (1.2). About complete affine maximal hypersurfaces there are two famous conjectures, one is the Chern’s conjecture (see [Ch]); another is a problem raised by ...
متن کاملSymplectic Automorphisms on Kummer Surfaces
Nikulin proved that the isometries induced on the second cohomology group of a K3 surface X by a finite abelian group G of symplectic automorphisms are essentially unique. Moreover he computed the discriminant of the sublattice of H(X,Z) which is fixed by the isometries induced by G. However for certain groups these discriminants are not the same of those found for explicit examples. Here we de...
متن کاملADIABATIC LIMITS OF RICCI - FLAT KÄHLER METRICS 3 from
We study adiabatic limits of Ricci-flat Kähler metrics on a Calabi-Yau manifold which is the total space of a holomorphic fibration when the volume of the fibers goes to zero. By establishing some new a priori estimates for the relevant complex Monge-Ampère equation, we show that the Ricci-flat metrics collapse (away from the singular fibers) to a metric on the base of the fibration. This metri...
