Generalized Bessel function of Type D
Nizar Demni
We write down the generalized Bessel function associated with the root system of type by means of multivariate hypergeometric series. Our hint comes from the particular case of…

First Hitting Time of the Boundary of the Weyl Chamber by Radial Dunkl Processes
Nizar Demni
We provide two equivalent approaches for computing the tail distribution of the first hitting time of the boundary of the Weyl chamber by a radial Dunkl process. The first approach…

Radial Dunkl Processes : Existence and uniqueness, Hitting time, Beta Processes and Random Matrices
Nizar Demni
We begin with the study of some properties of the radial Dunkl process associated to a reduced root system . It is shown that this diffusion is the unique strong solution for al…
