单位球上βP空间到Zα型空间的加权Cesàro算子(Extended Cesàro operators from βP spaces to Zα spaces on the unit ball)

Zhejiang Daxue xuebao. Lixue ban, 2013
Boundary and compact of extended Cesàro operators from βP spaces to Zygmund type space in the unit ball are studied. With the methods of functional analysis and several complex variables, the necessary and sufficient conditions are given for extended ...

Interpolation of compact non-linear operators

Journal of Inequalities and Applications, 2000
Let and be two Banach couples and let be a continuous map such that is a Lipschitz compact operator and is a Lipschitz operator. We prove that if is also compact or is continuously embedded in or is continuously embedded in , then is also a ...

Gudder–Nagy’s Theorem for Hilbert K(H)-Modules

Journal of Mathematics
We show in this paper Gudder–Nagy’s theorem for operators on Hilbert C∗-modules over C∗-algebra of compact operators. Let H be a complex Hilbert space with dim H>1, and KH the C∗-algebra of compact operators on H.

On the weak limit of compact operators on the reproducing kernel Hilbert space and related questions

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
By applying the so-called Berezin symbols method we prove a Gohberg- Krein type theorem on the weak limit of compact operators on the non- standard reproducing kernel Hilbert space which essentially improves the similar results of Karaev [5]: We also in ...

A Theory for Interpolation of Metric Spaces

Axioms
In this work, we develop an interpolation theory for metric spaces inspired by the real method of interpolation. These interpolation spaces preserve Lipschitz operators under certain conditions.

Multiplication Operators on Weighted Banach Spaces of a Tree

, 2015
We study multiplication operators on the weighted Banach spaces of an infinite tree. We characterize the bounded and the compact operators, as well as determine the operator norm.

Generalized bi-quasi-variational inequalities for quasi-semi-monotone and bi-quasi-semi-monotone operators with applications in non-compact settings and minimization problems

Journal of Inequalities and Applications, 2000
Results are obtained on existence theorems of generalized bi-quasi-variational inequalities for quasi-semi-monotone and bi-quasi-semi-monotone operators in both compact and non-compact settings.

Dual Toeplitz Operators on Bounded Symmetric Domains

Mathematics
We give some characterizations of dual Toeplitz operators acting on the orthogonal complement of the Bergman space over bounded symmetric domains. Our main result characterizes those finite sums of products of Toeplitz operators that are themselves dual ...
