Abstract
- In this paper, we are considered complex-valued neural networks (CVNNs) with unbounded time-varying delays and the problem of multiple μ-stability of the proposed CVNNs is extensively investigated. The choice of activation function is the main challenge in the analysis of CVNNs. Therefore, we chosen the real-imaginary-type activation function for the considered CVNNs. Some new sufficient conditions are derived to ensure that existence of [ ( 2 α + 1 ) ( 2 β + 1 ) ] n ( α , β ≥ 1 ) equilibrium points in which [ ( α + 1 ) ( β + 1 ) ] n equilibrium points are locally μ-stable and the remaining equilibrium points [ ( 2 α + 1 ) ( 2 β + 1 ) ] n − [ ( α + 1 ) ( β + 1 ) ] n are unstable for the considered CVNNs. Based on our main results, we can derive some stability conditions such as multiple exponential stability, multiple power stability, multiple log-stability and multiple log–log-stability. Finally, numerical example is presented to show the effectiveness of our theoretical results. [ABSTRACT FROM AUTHOR]
