Some Notes of Homogeneous Besov–Lorentz Spaces

open access: yesJournal of Mathematics, 2023
In this paper, we consider some properties of homogeneous Besov–Lorentz spaces. First, we get some relationship between B˙p0s,q,B˙p1s,qθ,r and Besov–Lorentz spaces, and then, we obtain the scaling property of B˙p,rs,q and F˙p,rs,q.

A generalization of a localization property of Besov spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
The notion of a localization property of Besov spaces is introduced by G. Bourdaud, where he has provided that the Besov spaces $B^{s}_{p,q}(\mathbb{R}^{n})$, with $s\in\mathbb{R}$ and $p,q\in[1,+\infty]$ such that $p\neq q$, are not localizable in the $\

Besov-type spaces for the κ-Hankel wavelet transform on the real line

open access: yesConcrete Operators, 2021
In this paper, we shall introduce functions spaces as subspaces of Lpκ (ℝ) that we call Besov-κ-Hankel spaces and extend the concept of κ-Hankel wavelet transform in Lpκ(ℝ) space.
