Characterizations of majorization on summable sequences

open access: yesFilomat, 2020
In this paper, we prove a necessary and sufficient condition for majorization on the summable sequence space. For this we redefine the notion of majorization on an infinite dimensional space and therein investigate properties of the majorization. We also prove the infinite dimensional Schur-Horn type and Hardy-Littlewood-P?lya type theorems.

MAJORIZING SEQUENCES FOR NEWTON'S METHOD

open access: yesTamkang Journal of Mathematics, 1998
Majorizing sequences for Newton's method are analysed from a new standpoint. As a consequence, we give convergence results under assumptions different from the classical Kantorovich conditions.

Majorization and multiplier sequences

open access: yesLinear Algebra and its Applications, 2011
The authors show the potential of matrix methods to study spectral properties of hyperbolic polynomials (i.e., polynomials having only real roots), and namely to study multiplier sequences (complex-valued sequences such that coefficient-wise multiplication preserves polynomial hyperbolicity).

Generalized Differentiability Conditions for Newton's Method. [PDF]

open access: yes, 2002
The use of majorizing sequences is the usual way to prove the convergence of Newton's method. An alternative technique to majorizing sequences is provided in this paper, in which three scalar sequences are used, so that the analysis of convergence is ...

Degree sequences and majorization

open access: yesLinear Algebra and its Applications, 1994
The authors define the majorization gap of a degree sequence as the minimum number of successive reverse-unit-transformations required to transform it into a threshold sequence (i.e., the degree sequence of a threshold graph). They deduce a formula for the majorization gap (by establishing a lower bound for it and exhibiting reverse-unit ...

A note on major sequences and external activity in trees [PDF]

open access: yesThe Electronic Journal of Combinatorics, 1996
A bijection is given from major sequences of length $n$ (a variant of parking functions) to trees on $\{0,\ldots,n\}$ that maps a sequence with sum ${{n+1}\choose 2} + k$ to a tree with external activity $k$.

On the Semi-Local Convergence of a Fifth-Order Convergent Method for Solving Equations

open access: yes, 2022
We study the semi-local convergence of a three-step Newton-type method for solving nonlinear equations under the classical Lipschitz conditions for first-order derivatives.
