关于Nielsen数的注记
A Note of Nielsen number
【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.
