Some Generalized Versions of Chevet–Saphar Tensor Norms

open access: yesMathematics, 2022
The paper is concerned with some generalized versions gE and wE of classical tensor norms. We find a Banach space E for which gE and wE are finitely generated tensor norms, and show that gE and wE are associated with the ideals of some E-nuclear ...

A New Paranormed Sequence Space Defined by Regular Bell Matrix

open access: yesDera Natung Government College Research Journal, 2023
This paper aims to construct a new paranormed sequence space by the aid of a regular matrix of Bell numbers. As well, its special duals such as α−,β−,γ−  duals are presented and Schauder basis is determined.

Some New Characterizations and g-Minimality and Stability of g-Bases in the Hilbert Spaces

open access: yesJournal of Function Spaces and Applications, 2013
The concept of g-basis in the Hilbert spaces is introduced by Guo (2012) who generalizes the Schauder basis in the Hilbert spaces. g-basis plays the similar role in g-frame theory to that the Schauder basis plays in frame theory.

Note on bases in algebras of analytic functions on Banach spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
Let $\{P_n\}_{n=0}^\infty$ be a sequenceof continuous algebraically independent  homogeneous polynomials on a complex Banach space $X.$ We consider the following question: Under which conditions polynomials $\{P_1^{k_1}\cdots P_n^{k_n}\}$ form a Schauder

g-Bases in Hilbert Spaces

open access: yesAbstract and Applied Analysis, 2012
The concept of g-basis in Hilbert spaces is introduced, which generalizes Schauder basis in Hilbert spaces. Some results about g-bases are proved. In particular, we characterize the g-bases and g-orthonormal bases. And the dual g-bases are also discussed.

Fractional integrals, derivatives and integral equations with weighted Takagi–Landsberg functions

open access: yesNonlinear Analysis, 2020
In this paper, we find fractional Riemann–Liouville derivatives for the Takagi–Landsberg functions. Moreover, we introduce their generalizations called weighted Takagi–Landsberg functions, which have arbitrary bounded coefficients in the expansion under ...
