亚幂零流形上映射的Nielsen Zeta函数是有理的

Nielsen zeta functions for maps on infra-nilmanifolds are rational

Karel Dekimpe, Gert-Jan Dugardein

摘要:

本文证明了对于亚零流形上的任意映射$f$,该映射的Nielsen数$N(f)$要么等于$|L(f)|$,其中$L(f)$是该映射的莱夫谢茨数,要么等于表达式$|L(f)-L(f_+)|$,其中$f_+$是$f$到该亚零流形的2-重覆盖的提升.通过利用这个关系的确切性质的所有权力的$f$,我们证明了Nielsen动态zeta函数的一个映射的infra-nilmanifold总是一个有理函数。

英文摘要:

In this paper we will show that for any map $f$ on an infra-nilmanifold, the Nielsen number $N(f)$ of this map is either equal to $|L(f)|$, where $L(f)$ is the Lefschetz number of that map, or equal to the expression $|L(f)-L(f_+)|$, where $f_+$ is a lift of $f$ to a 2-fold covering of that infra-nilmanifold. By exploiting the exact nature of this relationship for all powers of $f$, we prove that the Nielsen dynamical zeta function for a map on an infra-nilmanifold is always a rational function.
