Nilpotent structures and collapsing Ricci-flat metrics on K3 surfaces

Differential Geometry 2018-07-26 v1 Algebraic Geometry

Abstract

We exhibit families of Ricci-flat Kahler metrics on K3 surfaces which collapse to an interval, with Tian-Yau and Taub-NUT metrics occurring as bubbles. There is a corresponding continuous surjective map from the K3 surface to the interval, with regular fibers diffeomorphic to either 3-tori or Heisenberg nilmanifolds.
