Fixed Point Theory: A Review [PDF]
arXiv, 2023 Fixed points represent equilibrium states, stability, and solutions to a range of problems. It has been an active field of research. In this paper, we provide an overview of the main branches of fixed point theory. We discuss the key results and applications.

A note on two fixed point problems
Journal of Complexity, 2007 We extend the applicability of the Exterior Ellipsoid Algorithm for approximating n-dimensional fixed points of directionally nonexpanding functions. Such functions model many practical problems that cannot be formulated in the smaller class of globally nonexpanding functions.

Approximate Equilibrium Problems and Fixed Points [PDF]
International Journal of Analysis, 2013 We find a common element of the set of fixed points of a map and the set of solutions of an approximate equilibrium problem in a Hilbert space. Then, we show that one of the sequences weakly converges. Also we obtain some theorems about equilibrium problems and fixed points.

Fixed point structures on a set-mapping pair and cartesian product
Annals of the West University of Timisoara: Mathematics and Computer Science, 2022 In this paper we study the following problem (Problem 4.2 in, I.A. Rus, Sets with structure, mappings and fixed point property: fixed point structures, Fixed Point Theory 23, No. 2 (2022), 689-706):

Tischler graphs of critically fixed rational maps and their applications [PDF]
, 2019 A rational map $f:\widehat{\mathbb{C}}\to\widehat{\mathbb{C}}$ on the Riemann sphere $\widehat{\mathbb{C}}$ is called critically fixed if each critical point of $f$ is fixed under $f$.

On solutions of inclusion problems and fixed point problems [PDF]
Fixed Point Theory and Applications, 2013 An inclusion problem and a fixed point problem are investigated based on a hybrid projection method. The strong convergence of the hybrid projection method is obtained in the framework of Hilbert spaces. Variational inequalities and fixed point problems of quasi-nonexpansive mappings are also considered as applications of the main results.

Annales Mathematicae Silesianae, 2023 In this paper we formulate a setvalued fixed point problem by combining four prevalent trends of fixed point theory. We solve the problem by showing that the set of fixed points is nonempty.

Exact Strongly Coupled Fixed Point in $g\varphi^4$ Theory
, 2015 We show explicitly how a strongly coupled fixed point can be constructed in scalar $g\varphi^4$ theory from the solutions to a non-linear eigenvalue problem.

Decidability Results for the Boundedness Problem
, 2014 We prove decidability of the boundedness problem for monadic least fixed-point recursion based on positive monadic second-order (MSO) formulae over trees.

Hybrid steepest iterative algorithm for a hierarchical fixed point problem
Fixed Point Theory and Applications, 2017 The purpose of this work is to introduce and study an iterative method to approximate solutions of a hierarchical fixed point problem and a variational inequality problem involving a finite family of nonexpansive mappings on a real Hilbert space. Further,
