Complex boundary value problems of nonlinear differential equations arise from scientific research, modeling of nonlinear phenomena, and optimal control of complex systems. This field of study has played a tremendous role in the study of real-world systems and the development of new technologies. Key research areas in this field include well-posedness of the mathematical models, functional analysis theories and methods, approximation theories, and computational methods for solving complex real-world problems.

We invite researchers to submit original research articles as well as review articles on various aspects of complex boundary value problems of nonlinear differential equations and their applications to science, technology, and engineering. Potential topics include, but are not limited to:

• Dynamics differential equations
• Nonlocal boundary value problems
• Functional differential equations on time scales
• Impulsive differential and integral equations
• Fractional-order differential equations
• Numerical analysis for nonlinear differential equations
• Fixed-point theory
• Topological method
• Partial ordering method
• Variational approach
• Analysis and control
• Applications in science, technology, and engineering
• Financial mathematics and models
• Semilinear elliptic equations and systems
• Partial differential equations and their applications
