ON DIVIDED-DIFFERENCE SEMIGROUPS [PDF]
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.

Symbolic computation of divided differences [PDF]
Divided differences are enormously useful in developing stable and accurate numerical formulas. For example, programs to compute f ( x )- f ( y ) as might occur in integration, can be notoriously inaccurate.

Generalized Iterative Method of Order Four with Divided Differences
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.

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
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
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)
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 ...
