Existence and global exponential stability of almost periodic solution for quaternion‐valued high‐order Hopfield neural networks with delays via a direct method

Abstract: This paper deals with the existence and global exponential stability of almost periodic solutions for quaternion‐valued high‐order Hopfield neural networks with delays by a direct approach. Based on the contraction mapping principle, sufficient conditions are derived to ensure the existence and uniqueness of almost periodic solutions for the networks under consideration. By constructing a suitable Lyapunov function, the global exponential stability criterion of the almost periodic solution are derived. Finally… Show more

“…The global stability of QVNNs with time‐varying delays has been investigated in Liu et al 19 By virtue of the Lyapunov function method, some sufficient criteria were derived to ensure the global μ$$ \mu $$‐stability of delayed QVNNs. Some more interesting results of QVNNs with a variety of delays were discussed in previous studies 20–24 …”

“…Some more interesting results of QVNNs with a variety of delays were discussed in previous studies. [20][21][22][23][24] We are well aware that the number of stable equilibrium points of NNs is of great importance for their practical applications. Based on the number of stable equilibrium points, the stability of NNs can be divided into two categories.…”

“…The prevalence of quaternion neural network (QNN) theory is uninterruptedly enhanced of late years 5–7 . Quaternion has a real part and three imaginary parts, so QNNs combine many advantages of real‐valued neural networks or complex‐valued neural networks; besides, QNNs also have some features that they do not have, such as processing high‐dimensional data and two‐ or three‐dimensional space affine transformation.…”

“…4 The prevalence of quaternion neural network (QNN) theory is uninterruptedly enhanced of late years. [5][6][7] Quaternion has a real part and three imaginary parts, so QNNs combine many advantages of real-valued neural networks or complex-valued neural networks; besides, QNNs also have some features that they do not have, such as processing high-dimensional data and two-or three-dimensional space affine transformation. QNNs are extensively applied in practical fields, like human motion modeling, 8 sensor fusion, 9 spacecraft attitude tracking, 10 and image encryption 11 ; therefore, it is of significant theoretical meaning and realistic worth to consider the characteristics.…”

“…From the Lyapunov functional method and some inequality techniques, Luo, Jiang and Wang [14] studied the anti-periodic solutions of a Clifford-valued high-order neural network with proportional lags. The almost periodic solution problem for a quaternion-valued neural networks has been investigated by Li and Xiang [15]. For more results for high-dimensional dynamic systems and networks systems, please see, e.g., references [16][17][18][19][20] and related references.…”
