“…During the past decades, the dynamical behavior of fractional-order neural networks has attracted tremendous attention of numerous authors. For example, Wang et al [18] investigated the global stability analysis of fractional-order Hopfield neural networks with time delay, Zhang et al [22] considered the Mittag-Leffler stability of fractional-order Hopfield neural networks, Wang et al [16] discussed the asymptotic stability of delayed fractional-order neural networks with impulsive effects, Wang et al [17] focused on the stability analysis of fractional-order Hopfield neural networks with time delays. For more detailed work, we refer the readers to [5,6,8,9,14,19].…”
