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:

• Fixed-point theory
• Topological method
• Partial ordering method
• Variational approach
• Nonlinear singular boundary value problem
• Impulsive differential and integral equations
• Fractional order differential equations
• Analysis and control
• Numerical simulation and convergence analysis
• Applications in science, technology, and engineering

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/aaa/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
