Stability of the solutions of nonlinear third order differential equations with multiple deviating arguments

Abstract

Abstract. In this paper, with use of Lyapunov functional, we investigate asymptotic stability of solutions of some nonlinear differential equations of third order with delay. Our results include and improve some wellknown results in the literature.
