Journal of Inequalities and Applications, 2020 In this paper, we introduce a modified Krasnoselski–Mann type iterative method for capturing a common solution of a split mixed equilibrium problem and a hierarchical fixed point problem of a finite collection of k-strictly pseudocontractive nonself ...

Global search algorithm for optimal control [PDF]
, 1970 Random-search algorithm employs local and global properties to solve two-point boundary value problem in Pontryagin maximum principle for either fixed or variable end-time problems. Mixed boundary value problem is transformed to an initial value problem.

New Existence Results for Fixed Point Problem and Minimization Problem in Compact Metric Spaces
Abstract and Applied Analysis, 2014 We first present some new existence theorems for fixed point problem and minimization problem in compact metric spaces without assuming that mappings possess convexity property.

Critical Theory of Non-Fermi Liquid Fixed Point in Multipolar Kondo Problem
Physical Review X, 2020 When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr^{3+} ions in a cubic environment would possess quadrupolar and octupolar, but no magnetic dipole, moments.

Hyper-extensions in metric fixed point theory [PDF]
J. Nonlinear Convex Anal. 16 (2015), 539-550, 2014 We apply a modern axiomatic system of nonstandard analysis in metric fixed point theory. In particular, we formulate a nonstandard iteration scheme for nonexpansive mappings and present a nonstandard approach to fixed-point problems in direct sums of Banach spaces.

Double solutions of three-point boundary-value problems for second-order differential equations
Electronic Journal of Differential Equations, 2004 A double fixed point theorem is applied to yield the existence of at least two nonnegative solutions for the three-point boundary-value problem for a second-order differential equation, $$displaylines{ y'' + f(y)=0,quad 0 leq t leq 1,cr y(0) =0,quad y(p)

On Caristi fixed point theorem for set-valued mappings [PDF]
arXiv, 2020 The aim of this paper is to discuss Penot's problem on a generalization of Caristi's fixed point theorem. We settle this problem in the negative and we present some new theorems on the existence of fixed points of set-valued mappings in ordered metric spaces.

Some problems in the fixed point theory
Advances in the Theory of Nonlinear Analysis and its Application, 2018 In this paper we present some of my favorite problems, all the time open, in the fixed point theory. Theseproblems are in connection with the following two: Which properties have the fixed point equations for which an iterative algorithm is convergent ?

Spin-gap fixed points in the double-chain problem [PDF]
Physical Review B, 1994 Applying the bosonization procedure to weakly coupled Hubbard chains we discuss the fixed points of the renormalization group flow where all spin excitations are gapful and a singlet pairing becomes the dominant instability.

Application of Fixed-Point Theory for a Nonlinear Fractional Three-Point Boundary-Value Problem
Mathematics, 2019 Throughout this paper, via the Schauder fixed-point theorem, a generalization of Krasnoselskii’s fixed-point theorem in a cone, as well as some inequalities relevant to Green’s function, we study the existence of positive solutions of a ...
