Journal ArticleDOI
Paley-Wiener Theorems for the Dunkl Transform and Dunkl Translation Operators
TL;DR: In this article, the authors used the Dunkl intertwining operator V_k and its dual V_tV_k to prove a Paley-Wiener theorem for the transform for functions and distributions.
Journal ArticleDOI
The dunkel intertwining operator on spaces of functions and distributions and integral representation of its dual
TL;DR: In this paper, it was shown that the Dunkl intertwining operator defined only on the space of polynomials on can also be extended to an operator on spaces of functions and distributions.
Journal ArticleDOI
Inversion of the Radon Transform on the Laguerre Hypergroup by using Generalized Wavelets
M.M. Nessibi,Khalifa Trimèche +1 more
TL;DR: In this paper, the Radon transform R α, α≥ 0, on the Laguerre hypergroup K ǫ = [0, ∞ + ∞[ǫ×ǫ] R, is characterized as a bijection from a space of infinitely differentiable and rapidly decreasing functions.
Journal ArticleDOI
Ranges and inversion formulas for spherical mean operator and its dual
TL;DR: In this article, the spherical mean operator R and its dual t R were considered and it was shown that the operators R and t R are transmutation operators on some spaces of functions.
Journal ArticleDOI
Transmutation operators and paley–wiener theorem associated with a singular differential-difference operator on the real line
TL;DR: In this paper, a singular differential-difference operator Λ on the real line was considered and a Laplace integral representation for the eigenfunctions of the operator was constructed.
