| 摘 要： | 设M是有末端奇点的n维正规代数簇,L是M上的丰富线丛,(M,L)的数字有效值为τ=uv(u,v是互素的正整数),σ:M→W是由(M,L)决定的Nef-值态射.通过研究τ的取值情况对(M,L)进行分类,给出了当u=n-1时,(M,L)的较完整的分类,推广了一些文献的结果. |

| Abstract: | Let M be a normal variety of dimension n with terminal singular it ies,L an ample line bundle on M,the effective value of(M,L) be τ=u v(u,v are coprime integers),σ:M→W be the Nef-value morphism of(M,L).The classification of(M,L) can be done by studying the value of τ,when u= n-1,the classification of(M,L),the results of other papers were extended. |
| Keywords: | projective variery Nef-value morphism ample line bundle |
