On the periodic solutions of certain class of eighth-order differential equations
The aim of this paper is to.investigate sufficient conditions (Theorem 1) for the nonexistence of nontrivial periodic Solutions of the autonomous equation (1.1) and (Theorem 2) the existence of periodic Solutions of the nonautonomous eguation (1.2).
