Enhancing Equation Solving: Extending the Applicability of Steffensen-Type Methods

open access: yesMathematics, 2023
Local convergence analysis is mostly carried out using the Taylor series expansion approach, which requires the utilization of high-order derivatives, not iterative methods.

Local convergence of the Gauss-Newton-Kurchatov method under generalized Lipschitz conditions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
We investigate the local convergence of the Gauss-Newton-Kurchatov method for solving nonlinear least squares problems. This method is a combination of Gauss-Newton and Kurchatov methods and it is used for problems with the decomposition of the operator.

Three-Step Derivative-Free Method of Order Six

open access: yesFoundations, 2023
Derivative-free iterative methods are useful to approximate the numerical solutions when the given function lacks explicit derivative information or when the derivatives are too expensive to compute.

Value distribution of meromorphic solutions of certain difference Painlevé III equations

open access: yesAdvances in Difference Equations, 2018
In this paper, we investigate the difference Painlevé III equations w(z+1)w(z−1)(w(z)−1)2=w2(z)−λw(z)+μ $w(z+1)w(z-1)(w(z)-1)^{2}=w^{2}(z)-\lambda w(z)+\mu$ ( λμ≠0 $\lambda\mu\neq 0$) and w(z+1)w(z−1)(w(z)−1)2=w2(z) $w(z+1)w(z-1)(w(z)-1)^{2}=w^{2}(z ...

Semi-Local Convergence of Two Derivative-Free Methods of Order Six for Solving Equations under the Same Conditions

open access: yesFoundations, 2022
We propose the semi-local convergence of two derivative-free, competing methods of order six to address non-linear equations. The sufficient convergence criteria are the same, making a direct comparison between them possible.

Extended Comparison between Two Derivative-Free Methods of Order Six for Equations under the Same Conditions

open access: yesFractal and Fractional, 2022
Under the same conditions, we propose the extended comparison between two derivative free schemes of order six for addressing equations. The existing convergence technique used the standard Taylor series approach, which requires derivatives up to order ...

ON DIVIDED-DIFFERENCE SEMIGROUPS [PDF]

open access: yesInternational Journal of Algebra and Computation, 2011
The Newtonian divided-difference operators generate the nil-Coxeter algebra and semigroup. A bijective correspondence between the nil-Coxeter semigroup and the symmetric group is used to provide braid-like diagrams for the former, and corresponding Reidemeister-type moves for the relations.

On Some Properties of the Operator, Defined on Class of Analytic in the Half-Plane Functions

open access: yesNonlinear Analysis, 2004
In present paper the properties of the operator introduced by authors, which is defined on special class of n-normalized analytic in the half-plane functions are investigated. This operator is closely related with automorphism of a half-plane.
