摘要
本文通过运用Mawhiin迭合度理论,并采用分析变形方法和不等式变形技巧,得到了一类二阶的变时滞Cohen-Grossberg BAM神经网络系统周期解新的存在条件.
In this paper, by employing Mawhin coincidence degree theory and using the analysis methods,inequality technique, some new sufficient conditions were obtained to ensure the existence of the periodic solution to a second-order Cohen-Grossberg BAM neural networks with multiple time-varying delays.
