Multivariate Divided Differences. I: Basic Properties

open access: yesSIAM Journal on Numerical Analysis, 1992
Within the theory of spline functions, there is always great interest in divided differences, since they provide one possibility to define \(B\)- splines, i.e. splines with minimal support. In the paper under consideration, which is part of the author's doctoral thesis, a new type of generalization of the univariate divided differences to the ...

Generalized Iterative Method of Order Four with Divided Differences

open access: yesFoundations, 2023
Numerous applications from diverse disciplines are formulated as an equation or system of equations in abstract spaces such as Euclidean multidimensional, Hilbert, or Banach, to mention a few.

Improved Convergence Analysis of Gauss-Newton-Secant Method for Solving Nonlinear Least Squares Problems

open access: yesMathematics, 2019
We study an iterative differential-difference method for solving nonlinear least squares problems, which uses, instead of the Jacobian, the sum of derivative of differentiable parts of operator and divided difference of nondifferentiable parts. Moreover,

Local convergence for composite Chebyshev-type methods

open access: yesCommunications in Advanced Mathematical Sciences, 2018
We replace Chebyshev's method for solving equations requiring the second derivative by a Chebyshev-type second derivative free method. The local convergence analysis of the new method is provided using hypotheses only on the first derivative in contrast ...

Improving Convergence Analysis of the Newton–Kurchatov Method under Weak Conditions

open access: yesComputation, 2020
The technique of using the restricted convergence region is applied to study a semilocal convergence of the Newton−Kurchatov method. The analysis is provided under weak conditions for the derivatives and the first order divided differences ...

The tests of the belonging of functions to the classes Fn(D) and Qn(D)

open access: yesLietuvos Matematikos Rinkinys, 2021
In the work with the aid of the divided and finite differences are introduced classes Fn(D) and Qn(D) of functions holomorphic in region D. Different properties of functions from these classes are studied, the tests of the belonging of functions to the ...

Finitely defined functionals and divided differences

open access: yesJournal of Numerical Analysis and Approximation Theory, 2004
We give a necessary and sufficient condition for representing finitely defined functionals in terms of divided differences. As particular cases we obtain formulas of Tiberiu Popoviciu, Newton, etc.

Further Properties of Quantum Spline Spaces

open access: yesMathematics, 2020
We construct q-B-splines using a new form of truncated power functions. We give basic properties to show that q-B-splines form a basis for quantum spline spaces.
