Article Citation - Scopus: 25Some Generalizations of Darbo’s Theorem and Applications To Fractional Integral Equations(Springer International Publishing, 2016) Jleli,M.; Karapinar,E.; O’Regan,D.; Samet,B.In this paper, some generalizations of Darbo’s fixed point theorem are presented. An existence result for a class of fractional integral equations is given as an application of the obtained results. © 2016, Jleli et al.Conference Object Citation - Scopus: 1On (α, Ψ) Contractions of Integral Type on Generalized Metric Spaces(Springer International Publishing, 2015) Karapinar,E.In this paper, we investigate the existence and uniqueness of fixed points of (α,ψ)-contractive mappings of integral type in complete generalized metric spaces, introduced by Branciari. Our results generalize and improve several results in literature. © 2015 Springer International Publishing Switzerland.Book Citation - Scopus: 113Fixed Point Theory in Metric Type Spaces(Springer International Publishing, 2016) Agarwal,R.P.; Karapinar,E.; O’regan,D.; Roldán-López-De-Hierro,A.F.Written by a team of leading experts in the field, this volume presents a self-contained account of the theory, techniques and results in metric type spaces (in particular in G-metric spaces); that is, the text approaches this important area of fixed point analysis beginning from the basic ideas of metric space topology. The text is structured so that it leads the reader from preliminaries and historical notes on metric spaces (in particular G-metric spaces) and on mappings, to Banach type contraction theorems in metric type spaces, fixed point theory in partially ordered G-metric spaces, fixed point theory for expansive mappings in metric type spaces, generalizations, present results and techniques in a very general abstract setting and framework. Fixed point theory is one of the major research areas in nonlinear analysis. This is partly due to the fact that in many real world problems fixed point theory is the basic mathematical tool used to establish the existence of solutions to problems which arise naturally in applications. As a result, fixed point theory is an important area of study in pure and applied mathematics and it is a flourishing area of research. © David Ralph 2015.Article Citation - Scopus: 16Some Applications of Caristi’s Fixed Point Theorem in Metric Spaces(Springer International Publishing, 2016) Khojasteh,F.; Karapinar,E.; Khandani,H.In this work, partial answers to Reich, Mizoguchi and Takahashi’s and Amini-Harandi’s conjectures are presented via a light version of Caristi’s fixed point theorem. Moreover, we introduce the idea that many of known fixed point theorems can easily be derived from the Caristi theorem. Finally, the existence of bounded solutions of a functional equation is studied. © 2016 Khojasteh et al.
