We calculate the automorphism group of certain Enriques surfaces. The Enriques surfaces that we investigate include very general n-nodal Enriques surfaces and very general cuspidal Enriques surfaces. We also describe the action of the automorphism group on the set of smooth rational curves and on the set of elliptic fibrations.

某些 Enriques 曲面的自同构群

我们计算某些 Enriques 曲面的自同构群。我们研究的 Enriques 曲面包括非常通用的n节点 Enriques 曲面和非常通用的尖角 Enriques 曲面。我们还描述了自同构群对平滑有理曲线集和椭圆纤维化集的作用。
