Fixed Point Theory: Theory, Computation and Applications

This thematic series is devoted to the latest achievements in fixed point theory, computation and applications. It will reflect both  state-of-the-art
abstract research as well as important recent advances in computation and applications.

One of the most dynamic area of research of the last 50 years, fixed point theory plays a fundamental role in several theoretical and applied areas, such as nonlinear analysis, integral and differential equations and inclusions, dynamic systems theory, mathematics of fractals, mathematical economics (game theory, equilibrium problems, optimization problems) and mathematical modeling. This thematic series will present relevant works related to the theory of fixed points and its various applications to pure, applied and computational mathematics. Special attention will be paid to the most important theories developed by Professor Ioan A. Rus and the Cluj-Napoca Fixed Point Theory School: the Picard operator theory, the fixed point structure theory and other aspects of fixed point theory.

    On some fixed point theorems in generalized metric spaces

    In this paper, we obtain some generalizations of fixed point results for Kannan, Chatterjea and Hardy-Rogers contraction mappings in a new class of generalized metric spaces introduced recently by Jleli and Sa...

    Rectangular cone b-metric spaces over Banach algebra and contraction principle

    Rectangular cone b-metric spaces over a Banach algebra are introduced as a generalization of metric space and many of its generalizations. Some fixed point theorems are proved in this space and proper examples...

    Fixed point theorems for F-expanding mappings

    Recently, Wardowski (Fixed Point Theory Appl. 2012:94, 2012) introduced a new concept of F-contraction and proved a fixed point theorem which generalizes the Banach contraction principle. Following this direction...

    Pseudo-metric space and fixed point theorem

    The aim of this paper is to give a generalized version of Caristi fixed point theorems in pseudo-metric spaces. Our results generalize and improve many of well-known theorems. As an application of our results,...

    Random fixed point theorems in partially ordered metric spaces

    We present the random version in partially ordered metric spaces of the classical Banach contraction principle and some of its generalizations to ordered metric spaces.

    Contributions to the fixed point theory of diagonal operators

    In this paper, we introduce the notion of diagonal operator, we present the historical roots of diagonal operators and we give some fixed point theorems for this class of operators. Our approaches are based on...

    On multiplicative metric spaces: survey

    The purpose of this survey is to prove that the fixed point results for various multiplicative contractions are in fact equivalent to the corresponding fixed point results in (standard) metric spaces. For exam...

    Some fixed point results via R-functions

    We establish existence and uniqueness of fixed points for a new class of mappings, by using R-functions and lower semi-continuous functions in the setting of metric spaces. As consequences of this results, we obt...

    A note on recent cyclic fixed point results in dislocated quasi-b-metric spaces

    The purpose of this paper is to establish some fixed point results for cyclic contractions in the setting of dislocated quasi-b-metric spaces. We verify that some previous cyclic contraction results in dislocated...
