By using the direct method of Lyapunov and constructing a complete Lyapunov function, sufficient conditions which guarantee the convergence of solutions are obtained.</p>}, number={2}, journal={Journal of the Nigerian Mathematical Society}, author={Omonigho, Omeike Mathew}, year={2022}, month={Oct.}, pages={143–150} }
