Topological classification of Morse-Smale diffeomorphisms without heteroclinic curves on 3-manifolds
Ch Bonatti, V Grines, F Laudenbach +1
We show that, up to topological conjugation, the equivalence class of a Morse-Smale diffeomorphism without heteroclinic curves on 3-manifold is completely defined by an em- bedding…
Dynamically ordered energy function for Morse-Smale diffeomorphisms on 3-manifolds
Viatcheslav Grines, Francois Laudenbach, Olga Pochinka
This note deals with arbitrary Morse-Smale diffeomorphisms in dimension 3 and extends ideas from \cite{GrLaPo}, \cite{GrLaPo1}, where gradient-like case was considered. We introduc…
Quasi-energy function for diffeomorphisms with wild separatrices
Viatcheslav Grines, Francois Laudenbach, Olga Pochinka
According to Pixton, there are Morse-Smale diffeomorphisms of the 3-sphere which have no energy function, that is a Lyapunov function whose critical points are all periodic points…
Essential curves in handlebodies and topological contractions
Viatcheslav Grines, François Laudenbach
If is a compact set, a {\it topological contraction} is a self-embedding such that the intersection of the successive images , , consists of one point. In dime…
