Energy function as a complete topological invariant for gradient-like cascades on surfaces

V. E. Kruglov1, O. V. Pochinka2

AnnotationIn this paper we consider dynamical systems with discrete time generated by iterations of a gradient-like diffeomorphism of a surface whose non-wandering set consists of fixed points of positive type orientation. We prove that the class of topological conjugacy of such a system is completely determined by equivalence class of its energy Morse function.
