Sharp estimates for the p-adic Hardy type operators on higher-dimensional product spaces

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we introduce the p-adic Hardy type operator and obtain its sharp bound on the p-adic Lebesgue product spaces. Meanwhile, an analogous result is computed for the p-adic Lebesgue product spaces with power weights.

Geometry of operator spaces.

open access: yesMichigan Mathematical Journal, 1994
The authors investigate the position of \(K(X, Y)\), the space of compact linear operators between Banach spaces \(X\) and \(Y\), in \(L(X, Y)\), the space of bounded linear operators. The position is characterized in terms of M-ideals and unique Hahn-Banach extensions of continuous linear functionals from \(K(X, Y)\) to \(L(X, Y)\). In particular, the

Coerciveness and isomorphism of discontinuous Sturm-Liouville problems with transmission conditions

open access: yesJournal of New Results in Science
This study investigates a discontinuous Sturm-Liouville boundary value problem(BVP) on two intervals with functionals and transmission conditions in the direct sum ofSobolev spaces. Moreover, it presents the differential operator generated by the problem

Composition and multiplication operators between Orlicz function spaces

open access: yesJournal of Inequalities and Applications, 2016
Composition operators and multiplication operators between two Orlicz function spaces are investigated. First, necessary and sufficient conditions for their continuity are presented in several forms.

Boundedness for Commutators of Rough p-Adic Hardy Operator on p-Adic Central Morrey Spaces

open access: yesJournal of Function Spaces, 2021
In the present article we obtain the boundedness for commutators of rough p-adic Hardy operator on p-adic central Morrey spaces. Furthermore, we also acquire the boundedness of rough p-adic Hardy operator on Lebesgue spaces.

Operator Lipschitz functions on Banach spaces

open access: yes, 2016
Let $X$, $Y$ be Banach spaces and let $\mathcal{L}(X,Y)$ be the space of bounded linear operators from $X$ to $Y$. We develop the theory of double operator integrals on $\mathcal{L}(X,Y)$ and apply this theory to obtain commutator estimates of the form $\

Dirac operators on coset spaces [PDF]

open access: yesJournal of Mathematical Physics, 2003
The Dirac operator for a manifold Q, and its chirality operator when Q is even dimensional, have a central role in noncommutative geometry. We systematically develop the theory of this operator when Q=G/H, where G and H are compact connected Lie groups and G is simple.

New Results on Boas–Bellman-Type Inequalities in Semi-Hilbert Spaces with Applications

open access: yesAxioms, 2023
In this article, we investigate new findings on Boas–Bellman-type inequalities in semi-Hilbert spaces. These spaces are generated by semi-inner products induced by positive and positive semidefinite operators.

Injectivity of Operator Spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1989
We study the structure of injective operator spaces and the existence and uniqueness of the injective envelopes of operator spaces. We give an easy example of an injective operator space which is not completely isometric to any C ∗ {C^\ast } -algebra.
