Harmonic analysis of functions almost periodic at infinity in Banach modules [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The article is devoted to homogeneous spaces of functions defined on a locally compact Abelian group and with their values in a complex Banach space.

Application of a New Class of Characteristic Function

open access: yesJournal of Harbin University of Science and Technology, 2021
In Banach space,considering introducing a new class of real characteristic functions fx + ty ( y) and fx + ty ( y) ,the independent variable is t,and the domain is [0,+ ∞ ) ,and the corresponding properties of those new characteristic functions are used ...

Vector-valued extensions of operators through multilinear limited range extrapolation

open access: yes, 2021
We give an extension of Rubio de Francia's extrapolation theorem for functions taking values in UMD Banach function spaces to the multilinear limited range setting. In particular we show how boundedness of an $m$-(sub)linear operator \[T:L^{p_1}(w_1^{p_1}

Design and properties of wave packet smoothness spaces [PDF]

open access: yes, 2019
We introduce a family of quasi-Banach spaces - which we call wave packet smoothness spaces - that includes those function spaces which can be characterised by the sparsity of their expansions in Gabor frames, wave atoms, and many other frame ...

On Pentagonal Controlled Fuzzy Metric Spaces with an Application to Dynamic Market Equilibrium

open access: yesJournal of Function Spaces, 2022
In this manuscript, we coined pentagonal controlled fuzzy metric spaces and fuzzy controlled hexagonal metric space as generalizations of fuzzy triple controlled metric spaces and fuzzy extended hexagonal b-metric spaces.

Żuk’s criterion for Banach spaces and random groups

open access: yesForum of Mathematics, Sigma, 2023
We prove a Banach version of Żuk’s criterion for groups acting on partite (i.e., colorable) simplicial complexes. Using this new criterion, we derive a new fixed point theorem for random groups in the Gromov density model with respect to several classes ...

Multipliers of Banach valued weighted function spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We generalize Banach valued spaces to Banach valued weighted function spaces and study the multipliers space of these spaces. We also show the relationship between multipliers and tensor product of Banach valued weighted function spaces.

Banach Lattice Structures and Concavifications in Banach Spaces

open access: yesMathematics, 2020
Let ( Ω , Σ , μ ) be a finite measure space and consider a Banach function space Y ( μ ) . We say that a Banach space E is representable by Y ( μ ) if there is a continuous bijection I : Y ( μ ...

Type and cotype of some Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
Type and cotype are computed for Banach spaces generated by some positive sublinear operators and Banach function spaces. Applications of the results yield that under certain assumptions Clarkson's inequalities hold in these spaces.
