曲面层模概型集中同构类的紧性

Finiteness of isomorphic classes in the set of moduli schemes of sheaves on a surface

Kimiko Yamada

摘要:

当一个非奇异复射影曲面$X$满足$K_X\sim 0$时,我们将证明在$X$上具有固定陈类$α$的$H$ -半稳定层的模概型集合中,作为抽象概型的同构类只有1000个,其中$H$遍历$X$上所有$α$ -类属极化的集合.

英文摘要:

When a non-singular complex projective surface $X$ satisfies that $K_X\sim 0$, we shall show that there are only finitely many isomorphic classes as abstract schemes in the set of moduli scheme of $H$-semistable sheaves with fixed Chern classes $α$ on $X$, where $H$ runs over the set of all $α$-generic polarizations on $X$.
