Center manifold and exponentially-bounded solutions
of a forced Newtonian system with dissipation
Luis Garcia & Hugo Leiva
Abstract:
We study the existence of exponentially-bounded solutions to
the following system of second-order ordinary differential equations with
dissipation:

where
and
are positive constants,
is a globally Lipschitz function, and
is a bounded and continuous function.
is a
symmetric matrix whose first eigenvalue
is equal to zero and the others are positive.
Under these conditions, we prove that for some values of
,
and
there exist a continuous manifold such that solutions starting
in this manifold are exponentially bounded.
Our results are applied to the spatial discretization of well-known
second-order partial differential equations with Neumann boundary
conditions.
