A note on preservation of spectra for two given operators [PDF]

Mathematica Bohemica, 2020
We study the relationships between the spectra derived from Fredholm theory corresponding to two given bounded linear operators acting on the same space.

Pseudospectra of the direct sum of linear operators in ultrametric Banach spaces

Қарағанды университетінің хабаршысы. Математика сериясы
In this paper, a characterization of essential pseudospectra of bounded linear operators on ultrametric Banach spaces over a spherically complete field was given and the notions of pseudospectra and condition pseudospectra of the direct sum of linear ...

The Singular Value Expansion for Arbitrary Bounded Linear Operators

Mathematics, 2020
The singular value decomposition (SVD) is a basic tool for analyzing matrices. Regarding a general matrix as defining a linear operator and choosing appropriate orthonormal bases for the domain and co-domain allows the operator to be represented as ...

Common Fixed Points of a Subfamily of a Nonexpansive Periodic Evolution Family on a Strictly Convex Banach Space

Journal of Mathematics, 2021
In this study, we establish some results for strong convergence of a sequence to a common fixed point of a subfamily of a nonexpansive and periodic evolution family of bounded linear operators acting on a closed and bounded subset J of a strictly convex ...

The rate of convergence of bounded linear processes on spaces of continuous functions

Journal of Numerical Analysis and Approximation Theory, 2023
Quantitative Korovkin-type theorems for approximation by bounded linear operators defined on \(C(X,d)\) are given, where \((X,d)\) is a compact metric space. Special emphasis is on positive linear operators.

Condition pseudospectrum in non-Archimedean Banach spaces [PDF]

Journal of Mahani Mathematical Research
In this article, we introduce and study the condition pseudospectrum of bounded linear operator pencils on non-Archimedean Banach spaces. We obtain a characterization of the condition pseudospectrum of bounded linear operator pencils on non-Archimedean ...

Continuity of Bounded Linear Operators on Normed Linear Spaces [PDF]

Formalized Mathematics, 2018
Summary In this article, using the Mizar system [1], [2], we discuss the continuity of bounded linear operators on normed linear spaces. In the first section, it is discussed that bounded linear operators on normed linear spaces are uniformly continuous and Lipschitz continuous.
