Kummer曲面是曲面T/I的极小去奇异,其中T是2维复环面,I是T上的对合自同构当且仅当T是阿贝尔曲面当且仅当它的相关Kummer曲面是代数的。Kummer曲面是K3曲面(具有不为零的全纯2-形的单连通光滑曲面)的经典例子之一,在K3曲面理论中起着至关重要的作用。在某种意义上,所有的Kummer曲面(分别为代数Kummer曲面)形成一个4(分别3)-20中的维子集(分别为19)-维K3-曲面族(分别为代数K3曲面)。
A Kummer surface is the minimal desingularization of the surface T/i, where T is a complex torus of dimension 2 and i the involution automorphism on T. T is an abelian surface if and only if its associated Kummer surface is algebraic. Kummer surfaces are among classical examples of K3-surfaces (which are simply-connected smooth surfaces with a nowhere-vanishing holomorphic 2-form), and play a crucial role in the theory of K3-surfaces. In a sense, all Kummer surfaces (resp. algebraic Kummer surfaces) form a 4 (resp. 3)-dimensional subset in the 20 (resp. 19)-dimensional family of K3-surfaces (resp. algebraic K3 surfaces).
