椭圆纤维化K3曲面的镜像

代数几何 2017-02-28 v2

摘要

我们研究一个双参数族的(一般)Picard秩为1818的K3曲面,它镜像于带截面的椭圆纤维化K3曲面的1818维族。该族的成员由三维代数环面中由方程y2+z+z1+x3+ax+b=0y^2+z+z^{-1} + x^3 + ax +b =0给出的超曲面的紧化给出,其中aabb为该族的参数。由Morrison先前的工作可知,这些曲面是来自椭圆曲线乘积的Kummer曲面的二重覆盖,我们显式地建立了这一联系。这进而给出了镜像于Picard秩为1的极化K3曲面的单参数K3曲面族的描述。我们已获悉本文结果已见于现有文献,相应的参考文献已添加在引言末尾。
