Approximation theorems connected with differential-difference operator
Chokri Abdelkefi, Safa Chabchoub
In the present paper, we propose to give an extension to the context of Dunkl theory of the notion of translation and in connection with this a corresponding extension of Taylor's…

Uncentered maximal function for elliptic partial differential operator
Chokri Abdelkefi, Safa Chabchoub
The present paper, we study in the harmonic analysis associated to the Weinstein operator, the boundedness on Lp of the uncentered maximal function. First, we establish estimates f…

Generalized Taylor formula with integral remainder for Besov-Dunkl spaces
Chokri Abdelkefi, Safa Chabchoub, Faten Rached
In the present paper, we propose to prove some properties and estimates of the integral remainder in the generalized Taylor formula associated to the Dunkl operator on the real lin…
