Selected Papers from the 10th International Conference 2009 on Nonlinear Functional Analysis and Applications
Journal of Inequalities and Applications volume 2010, Article number: 747463 (2011)
During the last three decades, the problems of nonlinear analysis are a contemporary and very exhaustively studied research area and their applications can be found in functional analysis, fixed-point theory, variational inequalities, convex analysis, optimization, differential and integral equations, engineering, mathematical statistics, mathematical physics, astrophysics, and many other fields.
One of the most important and significant area is fixed-point theory being very rich, interesting, and extremely applicable areas of mathematics. The new results on fixed-point theory are focused on the existence of fixed points of the classes of single-valued contractive, nonexpansive, accretive, monotone, fuzzy contractive mappings, and some kinds of multivalued mappings as well as extending the well-known results to more general spaces and applications in various areas of variational inequalities, complementarity problems, convex analysis, optimization, differential and integral equations, stability of functional, and applied sciences.
Inspired the importance of fixed-point theory and applications, since 1995, we have organized International Conference on Nonlinear Functional Analysis and Applications, which has been held at Gyeongsang National University, Chinju City, and Kyungnam University, Masan City, Korea, by the financial support of two universities, the Korean Mathematical Society, the Youngnam Mathematical Society, and the Korea Research Foundation and others. The purpose of this conference is to bring together leading researchers to achieve an international or higher level on the research of Nonlinear Functional Analysis with Applications and related topics and exchange recent new topics with each other. Especially, the 10th International Conference 2009 on Nonlinear Functional Analysis and Applications was held over the period July 27–31, 2009, at Gyengsang National University and Kyungnam University, Korea. Later, this conference will be held every two years.
Following these lines, this special issue of the Journal of Inequalities and Applications contains the selected 42 papers from the 10th International Conference 2009 on Nonlinear Functional Analysis and Applications as follows:
