The main result of this paper states that if \(F: T \times I \rightarrow T\) is a homotopy on 2-dimensional torus and \(\pi _{1}(T,x_{0}) = <u,v|[u,v]=1>\), then the one-parameter Lefschetz class L(F) of F is given by$$\begin{aligned} L(F) = \pm N(F)\alpha , \end{aligned}$$where N(F) is the one-parameter Nielsen number of F, and \(\alpha = [u] \in H_{1}(\pi _{1}(T),\mathbb {Z})\).

圆环上的一参数Lefschetz类同伦

本文的主要结果表明,如果\(F:T \ times I \ rightarrow T \)是二维圆环上的同伦,并且\(\ pi _ {1}(T,x_ {0})= <u ,v | [U,v] = 1> \) ,则单参数莱夫谢茨类大号˚F的)˚F由下式给出$$ \ {开始对准} L(F)= \时N(F)\阿尔法,\ {端对齐} $$其中ñ˚F)是一个参数数尼尔森的˚F,和\(\阿尔法= [U] \在H_ {1}(\ PI _ {1}(T),\ mathbb {Z})\)
