The approximation of linear operators [PDF]

open access: yesTransactions of the American Mathematical Society, 1971
Let L(E, F) be the vector space of all linear maps of E into F. Consider a subspace G of L(E, F) such as all continuous maps. In G distinguish a subspace H of maps which are to be approximated by members of a smaller subspace N of G. Thus we always have N^H^G^L^E, F).

Fuzzy strong $φ$-b-normed linear space for fuzzy bounded linear operators [PDF]

open access: yes, 2022
In this paper, concept of fuzzy continuous operator, fuzzy bounded linear operator are introduced in fuzzy strong $\phi$-b-normed linear spaces and their relations are studied. Idea of operator fuzzy norm is developed and completeness of BF(X,Y) is established.

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.

Formulae of Partial Reduction for Linear Systems of First Order Operator Equations [PDF]

open access: yes, 2010
This paper deals with reduction of non-homogeneous linear systems of first order operator equations with constant coefficients. An equivalent reduced system, consisting of higher order linear operator equations having only one variable and first order ...

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

Linear Operators That Preserve Two Genera of a Graph

open access: yesMathematics, 2020
If a graph can be embedded in a smooth orientable surface of genus g without edge crossings and can not be embedded on one of genus g − 1 without edge crossings, then we say that the graph has genus g.

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.

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∗-

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 ...
