A refinement of the Conley index and an application to the stability of hyperbolic invariant sets. (English) Zbl 0633.58040
The author considers a continuous flow on the locally compact Hausdorff space \(\Gamma\). It is known that the compact and isolated invariant set S of this flow possesses a Conley index [C. Conley, Isolated invariant sets and the Morse index (1978; Zbl 0397.34056); C. Conley and E. Zehnder, Physica A 124, 649-657 (1984; Zbl 0605.58015)], which is the homotopy type of a pointed compact space. The author shows that an additional structure can be used to define an additional invariant of S under continuation, which carries along some topology of S itself. In the case when a normally hyperbolic invariant manifold S is a retract of \(\Gamma\), he proves a global and topological continuation-theorem [see also N. Fenichel, Indiana Univ. Math. J. 21, 193-226 (1971; Zbl 0246.58015)].
