Comparative exploration on bifurcation behavior for integer-order and fractional-order delayed BAM neural networks

Abstract: In the present study, we deal with the stability and the onset of Hopf bifurcation of two type delayed BAM neural networks (integer-order case and fractional-order case). By virtue of the characteristic equation of the integer-order delayed BAM neural networks and regarding time delay as critical parameter, a novel delay-independent condition ensuring the stability and the onset of Hopf bifurcation for the involved integer-order delayed BAM neural networks is built. Taking advantage of Laplace transform, stabi… Show more

“…Tus, the smaller the fractional-order, the more drastic the instability of the function becomes. Tis assertion will be further investigated in comparison with other models [17] in future research, where the bifurcation properties of the fractional-order delay diferential cobweb model will be discussed as shown in the related articles [17][18][19][20][21] and then assessed for the practical implication of the bifurcation of price in the market.…”

“…Naturally, the impact of time delay on Hopf bifurcation has attracted great attention from numerous scholars. In recent years, the study on Hopf bifurcation for integer-order dynamical models is relatively mature, but the investigation on Hopf bifurcation for fractional-order dynamical models is very rare (see previous studies [26][27][28][29][30][31][32] ). In particular, the study on Hopf bifurcation of prey-predator models is even less (see previous works 33,34 ).…”

“…Importantly, in the implementation process of NNs, the transmission speed of the hardware devices used in the design is limited, and there may be delays encountered. Delay may have significant impacts on NNs, leading to unexpected complex dynamics [23][24][25][26][27][28][29][30][31][32][33][34]. For example, Zhou et al [24] deal with the global exponential stability for the MCGNN, and got several stability conditions.…”
