Some criteria for guaranteeing the instability of zero solution of the equation are given by using the Lyapunov-Krasovskii functional approach. Comparing with the previous literature, our result is new and complements some known results.eninfo:eu-repo/semantics/closedAccessVector Differential EquationFifth OrderInstabilityMultiple Deviating ArgumentsArticle
