On a classification of axiom A diffeomorphisms with codimension one basic sets and isolated saddles
Abstract
Let , , be a closed orientable -manifold and the set of axiom A diffeomorp\-hisms satisfying the following conditions: (1) has nontrivial basic sets each is either an orientable codimension one expanding attractor or an orientable codimension one contracting repeller, and other trivial basic sets which are sinks, sources, saddles; (2) the invariant manifolds of isolated saddles are intersected transversally. We classify the diffeomorphisms from up to the global conjugacy on non-wandering sets for the following subsets of where satisfies to the following conditions: () every nontrivial basic set of any is uniquely bunched, and there is at least one nontrivial attractor and at least one nontrivial repeller, i.e. ; () and all isolated saddles have the same Morse index belonging to . The subset satisfies to the following conditions: () any boundary point of is fixed; () a unique isolated saddle has Morse index different from . The subset satisfies to the following conditions: () any boundary point of is fixed; () a unique isolated saddle has Morse index belonging to . The classification is based on a description of topological structure of supporting manifolds .
