Orbit maps of local S¹- actions on manifolds of dimension less than five
Abstract
dc:description.abstract<p>A local S<sup>1</sup>-action on a topological space X is a decomposition of X into points and simple closed curves such that each element of the decomposition has an invariant neighborhood admitting an effective action of S<sup>1</sup> whose orbits are elements of the decomposition. Let M be a compact connected PL n-manifold without boundary, and suppose that n ≤ 4. Let M* be a PL manifold of dimension n-1 and f a PL open map from M onto M* whose fibers are circles or points. It is proved that f is the orbit map of a local S<sup>1</sup>-action on M.</p> <p>This work provides a setting in which the orbit structure of locally smooth S<sup>1</sup>-actions on PL 4-manifolds can be studied. Under certain conditions the orbit structure of such an action is shown to determine the action up to equivalence over the orbit space. More generally, given a 3-manifold M*, constructions are given for all locally smooth S<sup>1</sup>-actions with orbit space M* and with PL orbit maps.</p>
