✦ Synopsis


Suppose the solution x _= 0 is asymptotically stable. This fact can be proved by an appropriate positive definite Lyapunov function. In such cases we always can find a positive function a(t) for which lim a(t) = 0 and | ---*CO

In this paper we consider the nonlinear third-order quasi-linear differential equation and obtain some simple conditions for the existence of a periodic solution for it. In so doing we use the implicit function theorem to prove a theorem about the existence of periodic solutions and consider one ex
