Linear Operator Equations [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1959
where / is holomorphic on a(u, Ct) — a(v, Ct), and c is a suitable contour. In the present note we study the operator SG® defined by Sx = 'YJi=iuixvi, {ui} and {vj} being commutative subsets of Ct; but it is understood that {uj} need not commute with {vj}. In a generic way, we shall refer to such an operator as an "elementary operator."2 Of course this

Program Synthesis and Linear Operator Semantics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
For deterministic and probabilistic programs we investigate the problem of program synthesis and program optimisation (with respect to non-functional properties) in the general setting of global optimisation. This approach is based on the representation

On Structure of Infinite B*-Matrices over Normed Fields

open access: yesInventions, 2021
This article is devoted to the investigation of infinite B*-matrices and linear operators over normed fields. Their structure is studied in the paper. Ideals and centers of the corresponding to them B*-algebras are scrutinized.

Approximation of classes of periodic functions of several variables with given majorant of mixed moduli of continuity

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
In this paper, we continue the study of approximation characteristics of the classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables whose majorant of the mixed moduli of continuity contains both exponential and logarithmic multipliers.

Maximality of linear operators [PDF]

open access: yesRendiconti del Circolo Matematico di Palermo Series 2, 2018
We present maximality results in the setting of non necessarily bounded operators. In particular, we discuss and establish results showing when the "inclusion" between operators becomes a full equality.

Fuzzy differential subordination related to strongly Janowski functions

open access: yesApplied Mathematics in Science and Engineering, 2023
The research presented in this paper concerns the notion of geometric function theory called fuzzy differential subordination. Using the technique associated with fuzzy differential subordination, a new subclass of analytic functions related with the ...

Properties of Fuzzy Closed Linear Operator [PDF]

open access: yesEngineering and Technology Journal, 2019
In this paper we recall the definition of fuzzy norm of a fuzzy bounded linear operator and the fuzzy convergence of sequence of fuzzy bounded linear operators in order to prove the uniform fuzzy bounded theorem and fuzzy open mapping theorem.
