Primitive contractions of Calabi-Yau threefolds II

preprint2008arXivOpen access

Abstract

We construct 16 new examples of Calabi--Yau threefolds with Picard group of rank 1. Each of these examples is obtained by smoothing the image of a primitive contraction with exceptional divisor being a del Pezzo surface of degree 6, 7 or P1×P1\mathbb{P}^1\times \mathbb{P}^1.
