A global condition for quasi-random behavior in a class of conservative systems. (English) Zbl 0860.58027
In this paper two ODE systems of dimension 4 are considered both having a saddle-focus with a homoclinic connection. Conditions are given under which these Hamiltonian systems have an infinite number of “multibump” homoclinic solutions and their dynamic is chaotic.
