Proximal Gradient Method for Solving Bilevel Optimization Problems
Mathematical 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.

Fixed point theory and nonlinear problems [PDF]
Bulletin 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]
, 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 $f$.

A fixed-point problem with mixed-type contractive condition
, 2020 We consider a fixed-point problem for mappings involving a mixed-type contractive condition in the setting of metric spaces. Precisely, we establish the existence and uniqueness of fixed point using the recent notions of $F$-contraction and $(H,\varphi)$-

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

An Extension of a Problem of Fixed Point
, 2016 In this article, we extend the requirement of the Problem 9.2 proposed at Varna 2015 Spring Competition, both in terms of membership of the measure 𝛾, and the case for the problem for the ex-inscribed circle 𝐶. We also try to guide the student in the search and identification of the fixed point, for succeeding in solving any problem of this type.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Fixed points and the inverse problem for central configurations [PDF]
Topological Methods in Nonlinear Analysis, 2020 Central configurations play an important role in the dynamics of the $n$-body problem: they occur as relative equilibria and as asymptotic configurations in colliding trajectories. We illustrate how they can be found as projective fixed points of self-maps defined on the shape space, and some results on the inverse problem in dimension $1$, i.e ...

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):
