Journal of Function SpacesThis paper investigates the regularity criteria for the velocity field of three-dimensional shear-thinning fluids in the framework of Besov spaces. We obtain that when the specific negative exponent of the velocity field satisfies certain integrability ...

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

The theorems about traces and extensions for functions from Nikolsky-Besov spaces with generalized mixed smoothness [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2022 The theory of embedding of spaces of differentiable functions studies important relations of differential (smoothness) properties of functions in various metrics and has wide application in the theory of boundary value problems of mathematical ...

Composition operators from Zygmund spaces into Besov Zygmund-type spaces [PDF]
AUT Journal of Mathematics and ComputingIn this paper first, the boundedness and compactness of a composition operator from Zygmund space to Besov Zygmund-type space are studied. Then we study this concepts for this operator by using the hyperbolic-type analytic Besov Zygmund-type class.

A generalization of a localization property of Besov spaces
Karpatsʹkì 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 $\

Boundedness of multidimensional Hausdorff operator on Hardy-Morrey and Besov-Morrey spaces
Journal of Inequalities and Applications, 2016 In this paper, we establish some boundedness conditions for the multidimensional Hausdorff operator on the homogeneous Hardy-Morrey and on the Besov-Morrey space, and we extend some results in the recent papers by Jia and Wang, and by Mazzucato ...

Equivalent Characterization on Besov Space
Abstract and Applied Analysis, 2021 In this paper, we give an equivalent characterization of the Besov space. This reveals the equivalent relation between the mixed derivative norm and single-variable norm.
