The rapid growth of fixed point theory and its applications over the past 80 years has led to a number of scholarly essays that examine its nature and its importance in nonlinear analysis, applied mathematical analysis, economics, game theory, and so forth. Many authors devoted their attention to investigate its generalizations in various different directions of the celebrated Banach contraction principle. For example, an interesting direction of research is the extension of the Banach contraction principle to multivalued maps, known as Nadler’s fixed point theorem, Mizoguchi-Takahashi’s fixed point theorem, Berinde-Berinde’s fixed point theorem, and so on. Very recently, several new iterative methods for fixed points and equilibrium problems have been investigated. In the past decades, the equilibrium problem has extensively studied its applications in different areas of science and has been generalized to the vectorial equilibrium problems for single-valued or multivalued maps and applied to solve optimization problems, variational inequality problems, saddle point problems, complementary problems, bilevel problems, and semi-infinite problems.

We cordially and earnestly invite researchers to contribute their original and high quality research papers which will inspire the advance in fixed point theory, equilibrium problems, and optimization problems. Potential topics include, but are not limited to:

• Generalized existence theorems for fixed points
• Nonlinear problems related to fixed point theory
• Algorithms for fixed points
• Generalized Ekeland’s variational principle with applications to nonlinear analysis
• Generalizations of Knaster, Kuratowski, and Mazurkiewicz (simply, KKM) principle and their applications
• Variational inequality problems: existence, algorithms, and applications
• Equilibrium problems
• Complementarity problems
• Optimization problems
