The theory of nonlinear analysis with its relation to fixed point theory has emerged as a rapidly growing area of research because of its applications in differential equation, KKM theory, nonlinear ergodic theory, game theory, optimization problem, control theory, and so on. Also, the iterative methods for finding the approximate solutions of fixed point problems, variational problems, equilibrium problems, optimization problems, and split feasibility problems are very important and useful.

The aim of this special issue is to promote research and its applications in the area of nonlinear functional analysis and applications. It will reflect theoretical research and advanced applications.
