Trivial dynamics for a class of analytic homeomorphisms of the plane
A homeomorphism of the plane $h$ has trivial dynamics if every
positive orbit $\{ h^n (p)\}_{n\geq 0}$ is either convergent (to a
fixed point) or divergent (to infinity). The main result of this
paper says that the property of trivial dynamics can be decided by
computing the topological degree of $id -h$. In this result it is
assumed that $h$ is analytic in the real sense. Some applications
to difference equations and to periodic Newtonian differential
equations are obtained.
