Peixoto Graph of Morse–Smale Diffeomorphisms on Manifolds of Dimension Greater than Three

Let $M^n$ be a closed orientable manifold of dimension greater than three and $G_1(M^n)$ be the class of orientation-preserving Morse–Smale diffeomorphisms on $M^n$ such that the set of unstable separatrices of every $f\in G_1(M^n)$ is one-dimensional and does not contain heteroclinic orbits. We show that the Peixoto graph is a complete invariant of topological conjugacy in $G_1(M^n)$.
