In this paper, we study the structural stability of three-dimensional diffeomorphisms with source-sink dynamics. Here the role of source and sink is played by one-dimensional hyperbolic repeller and attractor. It is well known that in the case when the repeller and the attractor are solenoids (not embedded in the surface), the diffeomorphism is not structurally stable. The author proves that in the case when the attractor and the repeller are canonically embedded in a surface, the diffeomorphism is also not structurally stable.1 All the manifolds considered in the paper are assumed to be orientable and all diffeomorphisms are assumed to preserve orientation.2 A set A is called an attractor of a diffeomorphism f if it has a compact neighborhood) is called a basin of the attractor A. A repeller is defined as the attractor for f −1 . By a dimension of the attractor (repeller) we mean its topological dimension.
