Covering Relations for Multidimensional Dynamical 
Systems - II 
(1773K, .ps)

ABSTRACT.  We use a topological technique based on covering 
relations to prove the existence of chaotic orbits for certain 
Hamiltonian systems with several degrees of freedom. This paper 
relies on an earlier work of Zgliczynski and Gidea.
