The stability, boundedness and ultimately boundedness of solutions are studied. The technique of proofs involves defining an appropriate Lyapunov functional. The obtained results include and improve the results in the literature. © 2016 The Authoreninfo:eu-repo/semantics/openAccessAsymptotic StabilityBoundednessDelayLyapunov FunctionalThird OrderVector Differential SystemArticle
