Abstract

We prove that the metric completion of a canonical Ricci-flat Kähler metric on the nonsingular part of a projective Calabi–Yau variety X with ordinary double point singularities is a compact metric length space homeomorphic to the projective variety X itself. As an application, we prove a conjecture of Candelas and de la Ossa for conifold flops and transitions.
