Abstract In this paper, we introduce a family of one-dimensional maximal operators M κ , m $\mathscr{M}_{\kappa ,m}$ , κ ≥ 0 $\kappa \geq 0$ and m ∈ N ∖ { 0 } $m\in \mathbb{N}\setminus \{0\}$ , which includes the Hardy–Littlewood maximal op

In this paper, we consider the normalized Bessel function of index $\alpha > -\frac{1}{2}$, we find an integral representation of the term $x^nj_{\alpha+n}(x)j_\alpha(y)$. This allows us to establish a product formula for the generalized Hankel funct

Beurling–Hörmander's theorem related to Bessel–Struve transform

Autor: Selma Negzaoui

Publikováno v: Integral Transforms and Special Functions. 27:685-697

In this paper, we consider the Bessel–Struve transform FBSα and we establish an analogous of Beurling-Hormander's theorem for each α>−12. More precisely, we determine the form of nonzero functions satisfying weaken condition of Beurling–Horma
