Advances in Difference Equations, 2021 For finding a common fixed point of a finite family of G-nonexpansive mappings, we implement a new parallel algorithm based on the Ishikawa iteration process with the inertial technique. We obtain the weak convergence theorem of this algorithm in Hilbert

Anomalous Quantum Diffusion at the Superfluid-Insulator Transition
, 2002 We consider the problem of the superconductor-insulator transition in the presence of disorder, assuming that the fermionic degrees of freedom can be ignored so that the problem reduces to one of Cooper pair localization.

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 ...

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)

Existence of solutions for second-order differential equations and systems on infinite intervals
Electronic Journal of Differential Equations, 2009 We study the existence of nontrivial solutions to the boundary-value problem $$displaylines{ -u''+cu'+lambda u = f(x,u),quad -infty <x<+infty , cr u(-infty )=u(+infty ) =0 }$$ and to the system $$displaylines{ -u''+c_1u'+lambda _1u = f(x,u ...

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 ?

Fixed point approach to Basset problem
New Trends in Mathematical Science, 2017 In the present paper, a sufficient condition for existence and uniqueness of Basset problem is obtained. The theorem on existence and uniqueness is established. This approach permits us to use fixed point iteration method to solve problem for differential equation involving derivatives of nonlinear order.

Strong Convergence Theorems for the Generalized Split Common Fixed Point Problem
Journal of Applied Mathematics, 2012 We introduce the generalized split common fixed point problem (GSCFPP) and show that the GSCFPP for nonexpansive operators is equivalent to the common fixed point problem.
