Title:
Quasi-periodic motions in strongly dissipative forced systems
Abstract:
We consider a class of ordinary differential equations describing
one-dimensional systems with a quasi-periodic forcing term
and in the presence of large damping. We discuss the conditions
to be assumed on the mechanical force and the forcing term
for the existence of quasi-periodic solutions which have
the same frequency vector as the forcing.
