A New Method to Study the Periodic Solutions of the Ordinary Differential Equations Using Functional Analysis

In this paper, a new theorems of the derived numbers method to estimate the number of periodic solutions of first-order ordinary differential equations are formulated and proved. Approaches to estimate the number of periodic solutions of ordinary differential equations are considered. Conditions tha...
