摘要

一般的K3曲面作为n = 0,1,4的第n个Hirzebruch曲面的双覆盖，不是其他光滑曲面的双覆盖。基于双覆盖的分支轨迹和Hirzebruch曲面的纤维空间，给出了这种K3曲面是另一个光滑有理曲面的双覆盖的判据。

Double cover K3 surfaces of Hirzebruch surfaces

Abstract General K3 surfaces obtained as double covers of the n-th Hirzebruch surfaces with n = 0, 1, 4 are not double covers of other smooth surfaces. We give a criterion for such a K3 surface to be a double covering of another smooth rational surface based on the branch locus of double covers and fibre spaces of Hirzebruch surfaces.

期刊介绍： Advances in Geometry is a mathematical journal for the publication of original research articles of excellent quality in the area of geometry. Geometry is a field of long standing-tradition and eminent importance. The study of space and spatial patterns is a major mathematical activity; geometric ideas and geometric language permeate all of mathematics.
