Some properties of solutions of the homogeneous nonlinear second order differential equations

Abstract

In this paper we consider the following nonlinear homogeneous second order differential equations, \(F(x,y,y^{\prime},y^{\prime\prime})=0.\) We present for the solutions, \(y\in C^2[a,b]\), of this equation, extremal principle, Sturm-type, Nicolescu-type and Butlewski-type separation theorems.

Some applications and examples are given. Open problems are also presented.
