摘要

我们引入对数恩里克流形作为恩里克流形的奇异类比，概括了张五常提出的对数恩里克曲面的概念。然后，我们将重点放在对数恩里克流形亚族的性质上，这些亚族允许奇异交映流形的准（quasi/'etale）覆盖，我们给出了许多例子。

Logarithmic Enriques varieties

We introduce logarithmic Enriques varieties as a singular analogue of Enriques manifolds, generalizing the notion of log-Enriques surfaces introduced by Zhang. We focus then on the properties of the subfamily of log-Enriques varieties that admit a quasi-\'etale cover by a singular symplectic variety and we give many examples.
