Coble有理曲面

Coble Rational Surfaces

I. Dolgachev, D. -Q. Zhang

摘要:

一个光滑有理曲面X是Coble曲面,如果反正则线性系为空,而反双正则线性系为非空.本文将对这些X进行分类,并考虑X模自同构上负曲线个数的有限性问题。

英文摘要:

A smooth rational surface X is a Coble surface if the anti-canonical linear system is empty while the anti-bicanonical linear system is non-empty. In this note we shall classify these X and consider the finiteness problem of the number of negative curves on X modulo automorphisms.
