A new product formula involving Bessel functions

MA Boubatra, S Negzaoui, M Sifi - Integral Transforms and Special …, 2022 - Taylor & Francis
In this paper, we consider the normalized Bessel function of index α>− 1 2, we find an
integral representation of the term xnj α+ n (x) j α (y). This allows us to establish a product …

Translation operator and maximal function for the (k, 1)-generalized Fourier transform

SB Saïd, L Deleaval - Journal of Functional Analysis, 2020 - Elsevier
