In this paper, the exponential stability is investigated for a class of BAM neural networks with distributed delays and nonlinear impulsive operators. By using Lyapunov functions and applying the Razumikhin technique, delay–independent sufficient conditions ensuring the global exponential stability of equilibrium points are derived. These results can easily(More)
The notion of fractional derivatives, as is long familiar, has its commencement in an inquiry postured amid a correspondence in the middle of Leibnitz and L’hospital. The five millennium extremely ancient inquiry has turned into a significant zone of exploration. As of late, it has been demonstrated that the differential designs including derivatives of(More)
In this paper, we study the global asymptotic behavior for an impulsive bidirectional associative memory neural network with time-varying delays. The impulses are realized at fixed moments of time. The main stability criteria are proved by employing Lyapunov functions and the Razumikhin technique. An illustrative example is given to demonstrate the(More)
