Abstract: The present paper is devoted to the topological classification of one-dimensional basiń sets of diffeomorphisms satisfying Smale's axiom A and defined on orientable surfaces of negative Euler characteristic equipped with a metric of constant negative curvature. Using methods of Lobachevsky geometry, each perfect one-dimensional attractor of A-diffeomorphism is uniquely associated with a geodesic lamination on the surface. It is established that, in the absence of special pairs of boundary periodic points in the attractor, there exists a homeomorphism of the surface homotopic to the identity that maps unstable manifolds of the basic set points into leaves of the geodesic lamination. Moreover, from the method of constructing geodesic laminations it follows that if the diffeomorphisms whose non-wandering sets contain perfect spaciously situated attractors are homotopic, then the geodesic laminations corresponding to these attractors coincide.

Keywords: diffeomorphism, axiom $A$, perfect basiń set, attractor, repeller, geodesic lamination.
