Abstract: In this paper, a class of Cohen–Grossberg neural networks with time-varying delays are considered. Without assuming the boundedness, monotonicity, and differentiability of activation functions and any symmetry of interconnections, sufficient conditions for the existence and exponential stability of the periodic solutions are established. This is done using the coincidence degree theorem and differential inequality techniques. The results of this paper are new and complement previously known results.
