By means of the Lyapunov-Krasovskii functional approach, we obtained two new results on the topic.eninfo:eu-repo/semantics/closedAccessDelay Differential EquationFourth And Fifth OrderInstabilityLyapunov-Krasovskii FunctionalOn the Instability of Solutions of Nonlinear Delay Differential Equations of Fourth and Fifth OrderArticle
