In this paper we study smooth orientation-preserving free actions of the cyclic group $\mathbb Z/m$ on a class of $(n-1)$-connected $2n$-manifolds, $\sharp g (S^n \times S^n)\sharp \Sigma$, where $\Sigma$ is a homotopy $2n$-sphere. When $n=2$ we obtain a classification up to topological conjugation. When $n=3$ we obtain a classification up to smooth conjugation. When $n \ge 4$ we obtain a classification up to smooth conjugation when the prime factors of $m$ are larger than a constant $C(n)$.

高度连通的 2n 流形上的自由循环群动作

在本文中,我们研究了循环群 $\mathbb Z/m$ 在一类 $(n-1)$-connected $2n$-流形上的平滑方向保持自由动作,$\sharp g (S^n \次 S^n)\sharp\Sigma$,其中 $\Sigma$ 是一个同伦的 $2n$-球体。当 $n=2$ 时,我们获得了拓扑共轭的分类。当 $n=3$ 时,我们获得了平滑共轭的分类。当 $n \ge 4$ 当 $m$ 的质因子大于常数 $C(n)$ 时,我们获得了平滑共轭的分类。
