Fixed point structures on a set-mapping pair and cartesian product

open access: yesAnnals 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]

open access: yes, 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 $f$.

Exact Strongly Coupled Fixed Point in $g\varphi^4$ Theory

open access: yes, 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

open access: yes, 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

open access: yesFixed 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,

Existence, Data Dependence and Stability of Fixed Points of Multivalued Maps in Incomplete Metric Spaces

open access: yesAnnales 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.

Existence Result For a Model Coupling a Quasi-Linear Parabolic Equation and a Linear Hyperbolic System [PDF]

open access: yesarXiv, 2022
We prove globally-in-time existence of solution for a problem coupling the linear Lam\'e system and the quasi-linear Stokes equation. A solution of this global coupled problem is viewed as the fixed point of some non-linear operator $T$. We construct, using a regularization procedure, a sequence $(T^\epsilon)_\epsilon$ of auxiliary approximating ...

The Split Common Fixed Point Problem for -Strictly Pseudononspreading Mappings

open access: yesJournal of Applied Mathematics, 2013
We introduce and analyze the viscosity approximation algorithm for solving the split common fixed point problem for the strictly pseudononspreading mappings in Hilbert spaces.

Towards an Asymptotic-Safety Scenario for Chiral Yukawa Systems

open access: yes, 2009
We search for asymptotic safety in a Yukawa system with a chiral $U(N_L)_L\otimes U(1)_R$ symmetry, serving as a toy model for the standard-model Higgs sector.
