摘要翻译：
我们得到了一类非单连通的Calabi-Yau三元的详细分类，这类三元对弦现象学中的许多问题都有潜在的兴趣。这三重式是Schoen's Calabi-Yau三重式的商，它们是两个有理椭圆曲面P1上的纤维积。商是由一个自由作用的有限阿贝尔群保持纤维。我们的工作涉及有理椭圆曲面的受限有限自同构群的分类。

英文摘要：
  We obtain a detailed classification for a class of non-simply connected Calabi-Yau threefolds which are of potential interest for a wide range of problems in string phenomenology. These threefolds arise as quotients of Schoen's Calabi-Yau threefolds, which are fiber products over P1 of two rational elliptic surfaces. The quotient is by a freely acting finite abelian group preserving the fibrations. Our work involves a classification of restricted finite automorphism groups of rational elliptic surfaces.
