关于Nielsen数的注记

A Note of Nielsen number

    摘要
  • 摘要: 通过构造基本群的正规子群,得到有限复迭空间和自映射的提升.并定义了NL数,指出用NL数可以估算自映射的Nielsen数.

     

    Abstract: In this paper,the finite covering space and the advancements of the self-mapping are obtained by formation of normal subgroup of the fundamental group. And the N-L number is defined. The paper points out that the self-mapping Nielsen number can be estimated by using NL number.
