Аннотация:

We present in this paper the problem of convergence behavior of solutions of certain third-order nonlinear delay differential equations and obtained the sufficient conditions involved under which the solutions of the delay differential equation are convergent. An example is also given to demonstrate the correctness of the proposed approach which improves earlier results on delay differential equations.
