NATIONAL MATHEMATICS COLLOQUIUM

The next meeting of the National Mathematics Colloquium will be held on June 25, 2018 (Monday) at 16:00 in the Conference Room of the Institute of Mathematics and Informatics, Acad. G. Bonchev Street, Block 8

A talk on:

On Kobayashi’s conjecture for K3 surfaces and hyperkaehler manifolds

Everybody is invited.

Head of the Colloquium: Acad. P. Popivanov

Abstract. The Kobayashi pseudometric on a complex manifold M is the maximal pseudometric such that any holomorphic map from the Poincare disk to M is distance-decreasing. Kobayashi conjectured that this pseudometric vanishes on Calabi-Yau manifolds. Using ergodicity of complex structures, we prove this conjecture for all K3 surfaces and for most classes of hyperkaehler manifolds. This is a joint work with S. Lu and M. Verbitsky.
