Instability of a Fifth-Order Nonlinear Vector Delay Differential Equation with Multiple Deviating Arguments

الملخص EN

We study a fifth-order nonlinear vector delay differential equation with multiple deviating arguments.

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.
