Quasi-invariant convergence for double sequence

, 2020
In this paper we introduce the concept of quasi-invariant convergence and quasiinvariant statistical convergence of double sequence in a normed space and we shall present a characterization of a bounded sequence to be quasi-invariant convergent.

Cubically Convergent Iterations for Invariant Subspace Computation [PDF]

SIAM Journal on Matrix Analysis and Applications, 2004
Summary: We propose a Newton-like iteration that evolves on the set of fixed dimensional subspaces of \(\mathbb R^n\) and converges locally cubically to the invariant subspaces of a symmetric matrix. This iteration is compared in terms of numerical cost and global behavior with three other methods that display the same property of cubic convergence ...

Asymptotically J_σ-Equivalence of Sequences of Sets

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
In thisstudy, we introduce the concepts of Wijsman asymptotically J-invariant equivalence (WLJσ) ,Wijsman asymptotically strongly p-invariant equivalence([WLVσ)]p) and Wijsman asymptotically J*-invariant equivalence(WLJ*σ).

Convergence of Restarted Krylov Subspaces to Invariant Subspaces [PDF]

SIAM Journal on Matrix Analysis and Applications, 2004
The authors prove estimates for the angle (strictly spoken: for the containment gap) between a searched invariant subspace of a general \(n\times n\) matrix and the subspace generated by Krylov subspace methods like the Arnoldi algorithm or the biorthogonal Lanczos algorithm.

Wijsman lacunary invariant statistical convergence for triple sequences via Orlicz function

, 2020
In this paper, we generalized the Wijsman lacunary invariant statistical convergence of closed sets in metric space by introducing the Wijsman lacunary invariant statistical φ̃ convergence for the sets of triple sequences.

Convergence properties of end invariants [PDF]

Geometry & Topology, 2013
We prove a continuity property for ending invariants of convergent sequences of Kleinian surface groups. We also analyze the bounded curve sets of such groups and show that their projections to non-annular subsurfaces lie a bounded Hausdorff distance from geodesics joining the projections of the ending invariants.

Complete convergence of randomly weighted END sequences and its application

Journal of Inequalities and Applications, 2017
We investigate the complete convergence of partial sums of randomly weighted extended negatively dependent (END) random variables. Some results of complete moment convergence, complete convergence and the strong law of large numbers for this dependent ...

On the Solutions of a Fourth Order Difference Equation

Universal Journal of Mathematics and Applications, 2021
In this paper, we solve and study the global behavior of the well defined solutions of the difference equation $$x_{n+1}=\frac{x_{n}x_{n-3}}{Ax_{n-2}+Bx_{n-3}}, \quad n=0,1,...,$$ where $A, B>0$ and the initial values $x_{-i}$, $i\in\{0,1,2,3 ...

Bootstrap, Markov Chain Monte Carlo, and LP/SDP hierarchy for the lattice Ising model

Journal of High Energy Physics, 2023
Bootstrap is an idea that imposing consistency conditions on a physical system may lead to rigorous and nontrivial statements about its physical observables. In this work, we discuss the bootstrap problem for the invariant measure of the stochastic Ising

Precise Deviations for Disk Counting Statistics of Invariant Determinantal Processes [PDF]

, 2020
We consider two-dimensional determinantal processes which are rotation-invariant and study the fluctuations of the number of points in disks. Based on the theory of mod-phi convergence, we obtain Berry-Esseen as well as precise moderate to large ...
