Δ-convergence for proximal point algorithm and fixed point problem in CAT(0) spaces

open access: yesFixed Point Theory and Applications, 2019
In this paper, we prove the Δ-convergence of a modified proximal point algorithm for common fixed points in a CAT(0) space for different classes of generalized nonexpansive mappings including a total asymptotically nonexpansive mapping, a multivalued ...

General fixed-point method for solving the linear complementarity problem

open access: yesAIMS Mathematics, 2021
In this paper, we consider numerical methods for the linear complementarity problem (LCP). By introducing a positive diagonal parameter matrix, the LCP is transformed into an equivalent fixed-point equation and the equivalence is proved.

On the nonlinear implicit complementarity problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
In this paper, we consider a new class of implicit complementarity problem and study the existence of its solution. An iterative algorithm is also given to find the approximate solution of the new problem and prove that this approximate solution ...

The split common fixed point problem for infinite families of demicontractive mappings

open access: yesFixed Point Theory and Applications, 2018
In this paper, we propose a new algorithm for solving the split common fixed point problem for infinite families of demicontractive mappings. Strong convergence of the proposed method is established under suitable control conditions.

BSE’s, BSDE’s and fixed-point problems

open access: yesThe Annals of Probability, 2017
In this paper, we introduce a class of backward stochastic equations (BSEs) that extend classical BSDEs and include many interesting examples of generalized BSDEs as well as semimartingale backward equations. We show that a BSE can be translated into a fixed point problem in a space of random vectors.

Equilibrium problems and fixed point theory [PDF]

open access: yesFixed Point Theory and Applications, 2012
The fixed point theory is a well-established subject in the area of nonlinear analysis. The iterative method for solving the fixed point problem was considered from the origin of this problem. Namely, Cauchy, Liouville, Lipschitz, Peano, Fredholm, Picard, Banach, Browder, Helpern, Mann, Ishikawa, etc., have given different kinds of iterative methods ...

A dual problem to least fixed points

open access: yesTheoretical Computer Science, 1981
AbstractAfter a simple and convenient generalization of the notion of continuous functions and continuous lattices we answer the following question: when for a given element x of a complete lattice there is a least continuous function having x as a least fixed point?

Fixed point theory and nonlinear problems [PDF]

open access: yesBulletin of the American Mathematical Society, 1983
This survey paper by a person who helped to shape the field described in the title begins with historical remarks about the evolvement of (analytic) degree theory and its importance to nonlinear problems. Then the author outlines the degree theory for continuous maps in \({\mathbb{R}}^ n\).

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 $f$.

Generalized robust shrinkage estimator and its application to STAP detection problem [PDF]

open access: yes, 2014
Recently, in the context of covariance matrix estimation, in order to improve as well as to regularize the performance of the Tyler's estimator [1] also called the Fixed-Point Estimator (FPE) [2], a "shrinkage" fixed-point estimator has been introduced ...
