AI总结:
本文通过结合Vinberg算法与格论方法,对复quasi-polarized K3-表面上的大线条配置进行分类,并确定了线数的上界。
摘要:
我们将经典的Vinberg算法与arXiv:1706.05734 [math.AG]中的格论/算术方法相结合,给出了一个分类大规模复 quasi-polarized K3-表面线上配置的方法。我们应用该方法来分类所有具有至多Du Val奇点且至少32条线的复K3-octic表面。线数的上界为36,与光滑情况相同,如果奇点集非空,则最多有32条线。
英文摘要:
We combine classical Vinberg's algorithms with the lattice-theoretic/arithmetic approach from arXiv:1706.05734 [math.AG] to give a method of classifying large line configurations on complex quasi-polarized K3-surfaces. We apply our method to classify all complex K3-octic surfaces with at worst Du Val singularities and at least 32 lines. The upper bound on the number of lines is 36, as in the smooth case, with at most 32 lines if the singular locus is non-empty.
