## On a structure of non-wandering set of an Ω-stable 3-diffeomorphism possessing a hyperbolic attractor

This paper belongs to a series of papers devoted to the study of the structure of the non-wandering set of an A-diffeomorphism. We study such set NW(f) for an Ω-stable diffeomorphism f, given on a closed connected 3-manifold M3 . Namely, we prove that if all basic sets in NW(f) are trivial except attractors, then every non-trivial attractor is either one-dimensional non-orientable or two-dimensional expanding.
