摘要翻译:
构造了秩为1的Picard群的Calabi-Yau三元的16个新例子。这些例子中的每一个都是通过平滑一个本原压缩的图像而得到的,它的例外除数是一个6,7或$\mathbb{P}^1乘以\mathbb{P}^1$的del Pezzo曲面。

英文摘要:
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 $\mathbb{P}^1\times \mathbb{P}^1$.
