Sufficient Conditions of Existence of Unique Periodic Solutions for Second Order One-Dimension Equations

Abstract

In this work sufficient conditions of existence of unique periodic solutions for second order one-dimension equations are derived. The goal of the paper is not only in getting such results, but also in demonstration of new approach, which may be applied to more general class of differential equations, i.e. it may be considered not only second order, but also grater order differential equations.
