Algebras of Vector Functions over Normed Fields

open access: yesInventions, 2022
This article is devoted to study of vector functions in Banach algebras and Banach spaces over normed fields. A structure of their Banach algebras is investigated. Banach algebras of vector functions with values in ∗-algebras, finely regular algebras, B∗-

Metatimes, random measures and cylindrical random variables

open access: yesModern Stochastics: Theory and Applications, 2021
Metatimes constitute an extension of time-change to general measurable spaces, defined as mappings between two σ-algebras. Equipping the image σ-algebra of a metatime with a measure and defining the composition measure given by the metatime on the domain

Applications of uniform boundedness principle to matrix transformations

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2023
Using the uniform boundedness principle of Maddox, we characterize matrix transformations from the space $(\ell_{p}) _{T}$ to the spaces $m(\phi )$ and $n(\phi )$ for the case $1\leq p\leq \infty$, which correspond to bounded linear operators.

Hypercausal Linear Operators [PDF]

open access: yesSIAM Journal on Control and Optimization, 1984
Several different classes of hypercausal operators appear in linear system theory. This paper provides, for each pair of classes of hypercausal operators, necessary and sufficient conditions on the Hilbert resolution space to guarantee equality of the classes. In addition, the effect of similarity transforms on each class is studied.

Linear Operators That Preserve Arctic Ranks of Boolean Matrices

open access: yesMathematics, 2021
We study some properties of arctic rank of Boolean matrices. We compare the arctic rank with Boolean rank and term rank of a given Boolean matrix. Furthermore, we obtain some characterizations of linear operators that preserve arctic rank on Boolean ...

Steady-State Analysis of a Flexible Markovian Queue with Server Breakdowns

open access: yesEntropy, 2019
A flexible single-server queueing system is considered in this paper. The server adapts to the system size by using a strategy where the service provided can be either single or bulk depending on some threshold level c.

L0-Linear Modulus of a Random Linear Operator

open access: yesAbstract and Applied Analysis, 2014
We prove that there exists a unique L0-linear modulus for an a.s. bounded random linear operator on a specifical random normed module, which generalizes the classical case.

Fuzzy differential subordinations connected with the linear operator [PDF]

open access: yesMathematica Bohemica, 2021
We obtain several fuzzy differential subordinations by using a linear operator $\mathcal{I}_{m,\gamma}^{n,\alpha}f(z)=z+\sum\limits_{k=2}^{\infty}(1+\gamma( k-1))^nm^{\alpha}(m+k)^{-\alpha}a_kz^k$.

Certain subclasses of analytic functions defined by a new general linear operator

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
Hypergeometric functions are of special interests among the complex analysts especially in looking at the properties and criteria of univalent. Hypergeometric functions have been around since 1900’s and have special applications according to their own ...

Continuity of Linear Operators Commuting with Continuous Linear Operators [PDF]

open access: yesTransactions of the American Mathematical Society, 1967
1. Introduction. In [6] and [8] we showed that centralisers (that is operators commuting with multiplication) on certain Banach algebras are necessarily continuous. In the present paper we consider whether an operator on a Banach space commuting with a continuous or a closed operator must itself be continuous.
