In this paper we prove a result on the effective generation of pluri-canonical linear systems on foliated surfaces of general type. Fix a function P:0, then there exists an integer N>0 such that if (X,) is a canonical or nef model of a foliation of general type with Hilbert polynomial χ(X,𝒪X(mK))=P(m) for all m0, then |mK| defines a birational map for all mN.

关于叶面的两边有界

在本文中,我们证明了在普通类型的叶面上有效生成多元正典线性系统的结果。修复功能P0,则存在一个整数 ñ>0 这样,如果 X 是具有希尔伯特多项式的普通类型叶的规范模型或nef模型 χX𝒪Xķ=P 对全部 0, 然后 |ķ| 定义所有的两分图 ñ
