摘要

我们证明了光滑六次曲面K3的X⊂P中的最大圆锥数为285，而实六次曲面中的最大实圆锥数为261。在两个极值配置中，所有的二次曲线都是不可约的。§

We prove that the maximal number of conics in a smooth sextic K3-surface X ⊂ P is 285, whereas the maximal number of real conics in a real sextic is 261. In both extremal configurations, all conics are irreducible. §

期刊介绍： The Nagoya Mathematical Journal is published quarterly. Since its formation in 1950 by a group led by Tadashi Nakayama, the journal has endeavoured to publish original research papers of the highest quality and of general interest, covering a broad range of pure mathematics. The journal is owned by Foundation Nagoya Mathematical Journal, which uses the proceeds from the journal to support mathematics worldwide.
