This paper analyzes the stability, uniformly stability, asymptotically stability, boundedness,
uniformly boundedness and square integrability of solutions of a system of differential …

This paper provides sufficient conditions for the stability, asymptotic stability, uniform
stability, boundedness and uniformly boundedness of solutions of a certain class of second …

In this paper, we employ the second method of Lyapunov to examine sufficient conditions for
the uniform-ultimate boundedness of solutions and existence of at least one periodic …

We establish a set of conditions for the uniform-ultimate boundedness of solutions to a
certain system of second order differential equations with variable delay using Lypunov …

This paper deals with a nonlinear ordinary differential system of second order. In the paper,
qualitative properties of solutions of the system called asymptotic stability (AS), uniform …

In this article, we consider a system of ordinary differential equations (ODEs) of second order
with two variable time delays. We obtain new conditions for uniform ultimate bounded (UUB) …

We consider certain class of second order nonlinear nonautonomous delay differential
equations of the form $$ a (t) x^{\prime\prime}+ b (t) g (x, x^\prime)+ c (t) h (x (tr)) m …
