A Method of Combining Fixed Points [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
It is now well known that in the category of finite polyhedra the fixed point property is not preserved by the operations of suspension, Cartesian product, adjunction along a segment, and join. Thus far none of the examples given have involved polyhedra of dimension 2. It is shown in this paper that two fixed points x x and y

Hybrid Fixed-Point Fixed-Stress Splitting Method for Linear Poroelasticity

open access: yesGeosciences, 2019
Efficient and accurate poroelasticity models are critical in modeling geophysical problems such as oil exploration, gas-hydrate detection, and hydrogeology. We propose an efficient operator splitting method for Biot’s model of linear poroelasticity

Proximal Gradient Method for Solving Bilevel Optimization Problems

open access: yesMathematical and Computational Applications, 2020
In this paper, we consider a bilevel optimization problem as a task of finding the optimum of the upper-level problem subject to the solution set of the split feasibility problem of fixed point problems and optimization problems.

Existence, Uniqueness and Stability Analysis with the Multiple Exp Function Method for NPDEs

open access: yesMathematics, 2022
In this study, firstly, through an alternative theorem, we study the existence and uniqueness of solution of some nonlinear PDEs and then investigate the Ulam–Hyers–Rassias stability of solution. Secondly, we apply a relatively novel analytical technique,

Nonlinear Random Stability via Fixed-Point Method

open access: yesJournal of Applied Mathematics, 2012
We prove the generalized Hyers-Ulam stability of the following additive-quadratic-cubic-quartic functional equation f(x+2y)+f(x−2y)=4f(x+y)+4f(x−y)−6f(x)+f(2y)+f(−2y)−4f(y)−4f(−y) in various complete random normed spaces.

Inertial Method for Bilevel Variational Inequality Problems with Fixed Point and Minimizer Point Constraints

open access: yesMathematics, 2019
In this paper, we introduce an iterative scheme with inertial effect using Mann iterative scheme and gradient-projection for solving the bilevel variational inequality problem over the intersection of the set of common fixed points of a finite number of ...

Fixed Points by a New Iteration Method [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
The following result is shown. If T T is a lipschitzian pseudo-contractive map of a compact convex subset E E of a Hilbert space into itself and x 1 {x_1} is any point in E E , then a certain mean value sequence defined by

Chebyshev Inertial Iteration for Accelerating Fixed-Point Iterations [PDF]

open access: yes, 2020
A novel method which is called the Chebyshev inertial iteration for accelerating the convergence speed of fixed-point iterations is presented. The Chebyshev inertial iteration can be regarded as a valiant of the successive over relaxation or Krasnosel'ski\v{\i}-Mann iteration utilizing the inverse of roots of a Chebyshev polynomial as iteration ...

The Steady States of Antitone Electric Systems [PDF]

open access: yesarXiv, 2023
The steady states of an antitone electric system are described by an antitone function with respect to the componentwise order. When this function is bounded from below by a positive vector, it has only one fixed point. This fixed point is attractive for the fixed point iteration method.

A note on a fixed-point method for deconvolution [PDF]

open access: yesStatistics, 2016
In this paper we study a particular multidimensional deconvolution problem. The distribution of the noise is assumed to be of the form $G(dx) = (1 − \alpha)\delta(dx) + \alpha g(x)dx$, where $\delta$ is the Dirac mass at $0\in R^d$ , $g : R^d → [0, \infty)$ is a density and $\alpha \in [0, 1 2 [$.
