献给M教授宫西在他六十岁生日之际摘要。Coble曲面是一个光滑的有理射影曲面,它的反正则线性系统是空的,而反双正则线性系统是非空的。本文对Coble曲面进行了分类,并考虑了其上的负有理曲线的个数的有限性问题。
Dedicated to Professor M. Miyanishi on the occasion of his sixtieth birthday Abstract. A Coble surface is a smooth rational projective surface such that its anti-canonical linear system is empty while the anti-bicanonical linear system is nonempty. In this paper we shall classify Coble surfaces and consider the finiteness problem of the number of negative rational curves on it modulo automorphisms.
