我们分类的非辛自同构的阶6椭圆K3曲面与一个给定的椭圆bration交换。我们展示了如何他们的研究可以减少到3阶的非辛自同构的研究和本地分析的BER。特别地,我们确定了可能的xed轨迹,并给出了它们在奇异bers上的位置。当Picard晶格是固定的,我们表明,K3表面来镜像对。
We classify non-symplectic automorphisms of order 6 on elliptic K3 surfaces which commute with a given elliptic bration. We show how their study can be reduced to the study of non-symplectic automorphisms of order 3 and to a local analysis of the bers. In particular, we determine the possible xed loci and give their location on the singular bers. When the Picard lattice is xed, we show that K3 surfaces come in mirror pairs.
