Weighted inequalities and uncertainty principles for the -generalized Fourier transform

TR Johansen - International Journal of Mathematics, 2016 - World Scientific
We obtain several versions of the Hausdorff–Young and Hardy–Littlewood inequalities for
the (k, a)-generalized Fourier transform recently investigated at length by Ben Saïd …

Paley–Littlewood decomposition for sectorial operators and interpolation spaces

C Kriegler, L Weis - Mathematische Nachrichten, 2016 - Wiley Online Library
We prove Paley–Littlewood decompositions for the scales of fractional powers of 0‐sectorial
operators A on a Banach space which correspond to Triebel–Lizorkin spaces and the scale …

Sharp approximation theorems and Fourier inequalities in the Dunkl setting

DV Gorbachev, VI Ivanov, SY Tikhonov - Journal of Approximation Theory, 2020 - Elsevier
In this paper we study direct and inverse approximation inequalities in L p (R d), 1< p<∞,
with the Dunkl weight. We obtain these estimates in their sharp form substantially improving …

Some properties of the Riesz potentials in Dunkl analysis

C Abdelkefi, M Rachdi - Ricerche di Matematica, 2015 - Springer
In the present paper, we study first the behavior at infinity of the Riesz potential for Dunkl
transform of a non compactly supported function. Second, we give for 1< p ≤ q<+ ∞ 1< p≤ …

Fractional Integrals Associated with the One-Dimensional Dunkl Operator in Generalized Lizorkin Space

F Bouzeffour - Symmetry, 2023 - mdpi.com
This paper explores the realm of fractional integral calculus in connection with the one-
dimensional Dunkl operator on the space of tempered functions and Lizorkin type space …

[PDF][PDF] Generalized Besov spaces and their applications

T Kawazoe, H Mejjaoli - Tokyo Journal of Mathematics, 2012 - projecteuclid.org
We define and study the Bessel potential and inhomogeneous Besov spaces associated
with the Dunkl operators on $\mathbf {R}^ d $. As applications on these spaces we construct …

[PDF][PDF] Dunkl operators on Rd and uncentered maximal function

C Abdelkefi - J. Lie Theory, 2010 - heldermann-verlag.de
We consider Dunkl theory on Rd associated to a finite reflection group G. We establish first
an estimate for the Dunkl translation of the characteristic function of a closed ball with radius …

[PDF][PDF] Generalized homogeneous Besov spaces and their applications

H Mejjaoli - Serdica Mathematical Journal, 2012 - math.bas.bg
In this paper we define the homogeneous Besov spaces associated with the Dunkl
operators on Rd, and we give a complete analysis on these spaces and same applications …

Weighted function spaces and Dunkl transform

C Abdelkefi - Mediterranean journal of mathematics, 2012 - Springer
We introduce first weighted function spaces on R^ d using the Dunkl convolution that we call
Besov-Dunkl spaces. We provide characterizations of these spaces by decomposition of …
