固定一个素数p.我们证明了一个闭的可定向3-流形M允许Zp对不动点集S1的作用当且仅当M可以作为p-周期框架连杆L上的手术结果而得到,并且Zp自由地作用在L的分支上。我们证明了一个类似的定理自由Zp-行动。作为一个有趣的应用,我们证明了下面的,相当意外的结果:对任何上述M和任何奇素数p,H1(M,Zp)<$Zp。我们还证明了有理同调3-球面的2-周期性的一个类似判据。
Fix a prime integer p. We show that a closed orientable 3-manifold M admits an action of Zp with the fixed point set S1 if and only if M can be obtained as the result of surgery on a p-periodic framed link L and Zp acts freely on the components of L. We prove a similar theorem for free Zp-actions. As an interesting application, we prove the following, rather unexpected result: for any M as above and for any odd prime p, H1(M, Zp) ≠ Zp. We also prove a similar criterion of 2-periodicity for rational homology 3-spheres.
