Nonlinear functional analysis plays an important role in the study of nonlinear boundary value problems and complex systems arising from many real-world applications. It is concerned with the well-posedness of the mathematical models, the construction of approximate solutions, and the quality of the approximate solutions. Hence, it is important to develop novel nonlinear functional analysis theories and methods and to apply the theories and methods to tackle complex real-world problems.

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

• Discrete dynamics differential equations
• Nonlinear singular boundary value problem
• Nonlinear 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
