Special Issue Information

Dear Colleagues:

With the development of science and technology, complex networks can be seen everywhere in the real world. Examples include the Internet, social networks, neural networks, and many others. In recent years, complex networks have attracted the attention of scholars in many fields including mathematics, biology, engineering and sociology. How to model actual complex networks and study their dynamic behavior is a very interesting and important topic in the field of complex network research. In mathematics, complex networks are usually described by differential or difference equations. In addition, practical applications depend on its dynamic properties such as stability, synchronization, periodicity, etc.

In this Special Issue of Axioms, we aim to explore the latest research and developments in dynamic properties of complex network control systems described by differential or difference equations. We will feature high-quality papers that cover a range of topics, including stability, synchronization and consistency of complex networks.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Dynamic behaviors of complex networks in the real world and their applications;
  2. Dynamic properties of different complex dynamical networks.

I look forward to receiving your contributions.

Since the research of μ-synchronization helps to explore how complex networks (CNs) work together to produce complex behaviors, the μ-synchronization task for uncertain time-delayed CNs is studied in our work. Especially, bounded external perturbations and variable delays of unknown bounds containing coupling delays, internal delays, and pulse delays are all taken into consideration, making the model more general. Through the μ-stable theory together with the hybrid impulsive control technique, the problems caused by uncertain inner couplings, time-varying delays, and perturbations can be solved, and novel synchronization criteria are gained for the μ-synchronization of the considered CNs. Different from traditional models, it is not necessary for the coupling matrices to meet the zero-row-sum condition, and the control protocol relaxes the constraint of time delays on impulse intervals. Moreover, numerical experiments and image encryption algorithms are carried out to verify our theoretical results’ effectiveness. Full article

The work examines a seven-parameter, three-dimensional, autonomous, cubic nonlinear differential system. This system extends and generalizes the previously studied quadratic nonlinear Hopf–Langford-type systems. First, by introducing cylindrical coordinates in its phase space, we show that the regarded system can be reduced to a two-dimensional Liénard system, which corresponds to a second-order Liénard equation. Then, we present (in explicit form) polynomial first and second integrals of Liénard systems of the considered type identifying those values of their parameters for which these integrals exist. It is also proved that a generic Liénard equation is factorizable if and only if the corresponding Liénard system admits a second integral of a special form. It is established that each Liénard system corresponding to a Hopf–Langford system of the considered type admits such a second integral, and hence, the respective Liénard equation is factorizable.

This paper investigates the stability of predator–prey models within multi-patch environments, with a particular focus on the influence of cross-dispersion across patches. We apply Kirchhoff’s matrix tree theorem and Liapunov’s method to derive criteria related to the cross-dispersion topology, thus solving the challenge of determining global asymptotic stability conditions. The method incorporates realistic ecological interactions and spatial heterogeneity, offering a framework for stability analysis. Our findings demonstrate that an appropriate level of cross-dispersion can effectively mitigate oscillations and foster convergence toward equilibrium. Two numerical examples validate these theoretical results and demonstrate the feasibility and effectiveness of the model across multiple patches. Full article
