Periodic solutions of a class of dynamical systems of second order
The author presents and proves sufficient conditions for the existence of infinitely many periodic solutions with prescribed period for a class of dynamical systems of second order. The paper is well-written, but theoretical. No examples are given. It should be of interest and use to theoreticians working with dynamical systems.
