Local convergence of spectra and pseudospectra [PDF]

Journal of Spectral Theory, 2018
We prove local convergence results for the spectra and pseudospectra of sequences of linear operators acting in different Hilbert spaces and converging in generalised strong resolvent sense to an operator with possibly non-empty essential spectrum. We establish local spectral exactness outside the limiting essential spectrum, local

Ball convergence of Potra-Ptak-type method with optimal fourth order of convergence

Journal of Numerical Analysis and Approximation Theory, 2021
We present a local convergence analysis Potra-Ptak-type method with optimal fourth order of convergence in order to approximate a solution of a nonlinear equation. In earlier studies such as [1], [5]-[28] hypotheses up to the fourth derivative are used.

Local Convergence Analysis of a One Parameter Family of Simultaneous Methods with Applications to Real-World Problems

Algorithms, 2023
In this paper, we provide a detailed local convergence analysis of a one-parameter family of iteration methods for the simultaneous approximation of polynomial zeros due to Ivanov (Numer. Algor. 75(4): 1193–1204, 2017).

Local Convergence Analysis of FastICA

, 2006
The FastICA algorithm can be considered as a selfmap on a manifold. It turns out that FastICA is a scalar shifted version of an algorithm recently proposed. We put these algorithms into a dynamical system framework. The local convergence properties are investigated subject to an ideal ICA model.

Estimating the Local Radius of Convergence for Picard Iteration

Algorithms, 2017
In this paper, we propose an algorithm to estimate the radius of convergence for the Picard iteration in the setting of a real Hilbert space. Numerical experiments show that the proposed algorithm provides convergence balls close to or even identical to ...

Increasing the order of convergence of multistep methods for solving systems of equations under weak conditions

Annals of the West University of Timisoara: Mathematics and Computer Science, 2019
In the present paper, we consider a construction proposed in Xiao and Yin (2016) to improve the order of convergence of the method from p to p + 2m under weaker assumptions.
