In the recent years, nonlinear dynamics have attracted a rapidly growing attention in the fields of finance, economy, mathematical biology and many other disciplines. It is important to develop new theories and methods, as well as to modify and refine the well-known techniques for the analysis of new classes of problems. This special issue is concerned with all nonlinear dynamics phenomena, such as self-organization, multifeedback, asymptotic behavior, stability, oscillation, bifurcation, and chaotic nature, occurring in financial systems. We aim to provide a platform for the discussion of the major research challenges and achievements on financial systems. Theoretical as well as numerical results are welcome. Potential topics include, but are not limited to:

• Dynamical analysis of stability, chaos, and bifurcation on financial systems
• Time-delay financial systems
• Asymptotic behavior analysis
• Stochastic modeling and analysis
• Behavioral finance modeling
• Agent-based computational finance
• Financial diagnosis and control
• Financial time series modeling and forecasting
• Portfolio selection and optimization
• Asset pricing and arbitrage techniques
• Risk assessment and credit analysis
• Numerical computation and simulations
