| Abstract |
A second-order differential equation containing a large parameter is considered. Such an
equation can be interpreted as an equation of constrained oscillations of a mechanical system with one
degree of freedom, provided that the fundamental frequency of the system substantially exceeds the
external frequency. We provide a new proof of the existence of a periodic solution of that equation such
that it is close to the periodic solution of the corresponding degenerate equation. That proof is
obtained by means of the Poincaré method. |
