On Norm-Attainable Operators in Banach Spaces [PDF]
Journal of Function Spaces, 2020 Norm-attainable operators have been studied over a period of time with nice results obtained particularly in Hilbert spaces. In this work, we consider the Banach space setting by characterizing nonpower operators on H and elementary operators. Lastly, we

Tauberian Operators on Banach Spaces [PDF]
Proceedings of the American Mathematical Society, 1976 A Tauberian operator: E → F E \to F (Banach spaces) is one which satisfies T g ∈ F , g ∈ E Tg \in F,g \in E imply g ∈ E g \in E .

Some characterizations of surjective operators on banach lattices [PDF]
Journal of Hyperstructures, 2018 The concepts of compact and weakly compact operators on Banach spaces are considered and investigated in several papers. In this paper, taking idea from this notations, we consider the concept surjective compact and weakly compact operators on Banach ...

Iterative Schemes Involving Several Mutual Contractions
Mathematics, 2023 In this paper, we introduce the new concept of mutual Reich contraction that involves a pair of operators acting on a distance space. We chose the framework of strong b-metric spaces (generalizing the standard metric spaces) in order to add a more ...

Multiple summing operators on Banach spaces [PDF]
Journal of Mathematical Analysis and Applications, 2003 In this paper, we improve some previous results about multiple p-summing multilinear operators by showing that every multilinear form from spaces is multiple p-summing for 1 p 2. The proof is based on the existence of a predual for the Banach space of multiple p-summing multilinear forms. We also show the failure of the inclusion theorem in this class

Invertible Operators on Banach Spaces [PDF]
Formalized Mathematics, 2019 Summary In this article, using the Mizar system [2], [1], we discuss invertible operators on Banach spaces. In the first chapter, we formalized the theorem that denotes any operators that are close enough to an invertible operator are also invertible by using the property of Neumann series.

Composition Operators on Some Banach Spaces of Harmonic Mappings
Journal of Function Spaces, 2020 We study the composition operators on Banach spaces of harmonic mappings that extend several well-known Banach spaces of analytic functions on the open unit disk in the complex plane, including the α-Bloch spaces, the growth spaces, the Zygmund space ...

Parareflexive operators on Banach spaces. [PDF]
Michigan Mathematical Journal, 1990 The objective of this paper is to extend to a class of Banach spaces the results of \textit{C. Apostol}, \textit{R. G. Douglas} and \textit{C. Foiaş} on nilpotent operators and parareflexive operators on Hilbert spaces [Trans. Am. Math. Soc. 224 (1976), No. 2, 407-415 (1977; Zbl 0342.47008)]. The quasi-similarity of nilpotent operators to Jordan models
