Oriented {$Z\sb 4$} actions without stationary points
IntroductionLet Z 2 k denote the cyclic group of order 2 k (k^2).In [8], we have studied the theory W*(Z Z k',Af) of almost free Z 2 k actions on closed Wall manifolds, i. e., an element g^Z 2k has no fixed point on the manifolds unless g is 1 …
