The journal "Discontinuity, Nonlinearity, and Complexity" is an interdisciplinary platform that publishes original research and new findings on recent developments in discontinuity, nonlinearity, and complexity within the physical and social sciences. The aim of the journal is to stimulate research interest in exploring discontinuity, complexity, nonlinearity, and chaos in complex systems. We invite manuscripts on dynamical systems characterized by nonlinearity and chaos, which may include mathematical theories and methods, physical principles and laws, as well as computational techniques. This journal provides a venue for researchers to rapidly exchange ideas and techniques related to discontinuity, complexity, nonlinearity, and chaos in both physical and social sciences. Topics of interest include: complex and hybrid dynamical systems, discontinuous dynamical systems (e.g., impulsive, time-delay, flow barriers), nonlinear discrete systems and symbolic dynamics, fractional dynamical systems and control, stochastic dynamical systems and randomness, complexity, self-similarity, and synchronization in nonlinear physics, nonlinear phenomena and physical mechanisms, stability, bifurcation, and chaos in complex systems, hydrodynamics, turbulence, and complexity mechanisms, nonlinear waves and solitons, dynamical networks, combinatorial aspects of dynamical systems, biological dynamics and biophysics, pattern formation, social science, and complexity.
