The journal "Communications in Nonlinear Science and Numerical Simulation" publishes original research results related to experimental observations, mathematical modeling, theoretical analysis, and numerical simulations, aiming to more accurately describe, predict, or novelly apply nonlinear phenomena in science and engineering. It provides a platform for researchers to quickly exchange ideas and techniques in nonlinear science and complexity, particularly encouraging submissions that employ interdisciplinary approaches. Topics of interest include nonlinear differential or delay equations, Lie group analysis and asymptotic methods, discontinuous systems, fractals, fractional calculus and dynamics, nonlinear effects in quantum mechanics, nonlinear stochastic processes, experimental nonlinear science, time series and signal analysis, computational methods and simulations in nonlinear science and engineering, control of dynamical systems, synchronization, Lyapunov analysis, high-dimensional chaos and turbulence, chaos in Hamiltonian systems, integrable systems and solitons, collective behavior in many-body systems, biophysics and networks, nonlinear mechanical systems, and complexity in complex systems. There is no length restriction for contributions, but they should be concise. The journal also welcomes the publication of brief papers on a fast communication basis and discussions on previously published papers.
