On the convergence of second-order spectra and multiplicity [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
The notion of second-order relative spectrum of a self-adjoint operator acting on a Hilbert space has been studied recently in connection with the phenomenon of spectral pollution in the Galerkin method. In this paper we examine how the second-order spectrum encodes precise information about the multiplicity of the isolated eigenvalues of the ...

The Coming Multi-Order World [PDF]

open access: yes, 2016
The article shows that the current international system is changing towards a completely new form of international system, conceptualized as a multi-order system. The suggestion for a multi-order world stands in contrast to three current narratives about

Local convergence of a fifth convergence order method in Banach space

open access: yesArab Journal of Mathematical Sciences, 2017
We provide a local convergence analysis for a fifth convergence order method to find a solution of a nonlinear equation in a Banach space. In our paper the sufficient convergence conditions involve only hypotheses on the first Fréchet-derivative ...

Comparison between Two Competing Newton-Type High Convergence Order Schemes for Equations on Banach Spaces

open access: yesFoundations, 2023
We carried out a local comparison between two ninth convergence order schemes for solving nonlinear equations, relying on first-order Fréchet derivatives.

On some computational orders of convergence

open access: yesApplied Mathematics Letters, 2010
Two variants of the Computational Order of Convergence (COC) of an iterative method for solving nonlinear equations are presented. Furthermore, the way to approximate the COC and the new variants to the local order of convergence is analyzed. The new definitions given here does not involve the unknown root.

High-Order Hybrid Stratified Sampling: Fast Uniform-Convergence Fourier Transform Estimation [PDF]

open access: yes, 2018
This paper considers the problem of estimating the Fourier transform of continuous-time signals from N nonuniformly collected observations. Here, we introduce a new class of Hybrid Stratified sampling scheme in conjunction with a suitable estimator ...

Local convergence for multi-point-parametric Chebyshev-Halley-type methods of high convergence order

open access: yes, 2015
We present a local convergence analysis for general multi-point-Chebyshev-Halley-type methods (MMCHTM) of high convergence order in order to approximate a solution of an equation in a Banach space setting.

On the convergence of the combination technique [PDF]

open access: yes, 2013
Sparse tensor product spaces provide an efficient tool todiscretize higher dimensional operator equations. The direct Galerkin method in such ansatz spaces may employ hierarchical bases, interpolets, wavelets or multilevel frames. Besides, an alternative

Higher Order of Convergence with Multivalued Contraction Mappings

open access: yesJournal of Mathematics, 2020
In this paper, we establish some theorems of fixed point on multivalued mappings satisfying contraction mapping by using gauge function. Furthermore, we use Q- and R-order of convergence.
