TOPOLOGICAL CLASSIFICATION OF MORSE-SMALE DIFFEOMORPHISMS WITHOUT HETEROCLINIC INTERSECTIONS

摘要

We study the class G(M~n) of orientation-preserving Morse-Smale diffeomorfisms on a connected closed smooth manifold M~n of dimension n ≥ 4 which is defined by the following condition: for any f ∈ G(M~n) the invariant manifolds of saddle periodic points have dimension 1 and (n - 1) and contain no heteroclinic intersections. For diffeomorfisms in G(M~n) we establish the topoligical type of the supporting manifold which is determined by the relation between the numbers of saddle and node periodic orbits and obtain necessary and sufficient conditions for topological conjugacy.
