Moreover, we introduce an n-dimensional generalization of Bessel operator and we have studied its properties in relation to the Hankel transform. Moreover, we study some application to the study of the fractional powers of Bessel operator on .
Webin this case is the zero operator (Proposition 3.13). Finally, we introduce fractional powers of closed operators, as defined by Balakrishnan [2]. These provide a wide class of examples which illustrate our theory; a simple sufficient condition that the domain of the infinitesimal generator be dense is given. WebMSP — Nonprofit Math Publishing
