Fractional Bessel Derivative Within the Mellin Transform Framework

In this paper, we present a fresh perspective on the fractional power of the Bessel operator using the Mellin transform. Drawing inspiration from the work of Pagnini and Runfola, we develop a new approach by employing Tato’s type lemma for the Hankel transform. As an application, we establish a new intertwining relation between the fractional Bessel operator and the fractional second derivative, emphasizing the important role of the Mellin transform in the domain of fractional calculus associated with the Bessel operator.
