Applications of the Sylvester operator in the space of slice semi-regular functions

open access: yesConcrete Operators, 2020
In this paper we apply the results obtained in [3] to establish some outcomes of the study of the behaviour of a class of linear operators, which include the Sylvester ones, acting on slice semi-regular functions. We first present a detailed study of the

The Class of Demi-Strongly Order Bounded Operators

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
In this paper, we introduce the class of demi-strongly order bounded operators on a Riesz space generalization of strongly order bounded operators. Let M be a Riesz space, an operator H from M into M is said to be a demi-strongly order bounded operator ...

A Regular k-Shrinkage Thresholding Operator for the Removal of Mixed Gaussian-Impulse Noise

open access: yesApplied Computational Intelligence and Soft Computing, 2017
The removal of mixed Gaussian-impulse noise plays an important role in many areas, such as remote sensing. However, traditional methods may be unaware of promoting the degree of the sparsity adaptively after decomposing into low rank component and sparse

Bulk residual closure and boundary residual reduction for elliptic XYZ-type regular-derivative chains

open access: yesNuclear Physics B
We introduce a two-level residual construction for elliptic XYZ-type regular-derivative chains. The first level places a full two-spin Pauli W-envelope into the ordinary Yang–Baxter residual and closes the bulk sector, inside a nonsingular finite ...

Boundary-value problems for second-order differential operators with nonlocal boundary conditions

open access: yesElectronic Journal of Differential Equations, 2007
In this paper, we study a second-order differential operator combining weighting integral boundary condition with another two-point boundary condition.

Normed Dual Algebras

open access: yesMathematics, 2019
This article is devoted to the investigation of dual and annihilator normed algebras. Their structure is studied in the paper. Extensions of algebras and fields are considered and by using them, core radicals and radicals are investigated.

Ergodic conditions and spectral properties for A-contractions [PDF]

open access: yesOpuscula Mathematica, 2008
In this paper the canonical representation of an \(A\)-contraction \(T\) on a Hilbert space \(\mathcal{H}\) is used to obtain some conditions concerning the concept of \(A\)-ergodicity studied in [L.
