  • First Hitting Time of the Boundary of the Weyl Chamber by Radial Dunkl Processes 
    Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    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 is based on a spectral problem with initial ...
  • Generalized Bessel function of Type D 
    Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We write down the generalized Bessel function associated with the root system of type D by means of multivariate hypergeometric series. Our hint comes from the particular case of the Brownian motion in the Weyl chamber of type D.
  • Generalized Stieltjes Transforms of Compactly-Supported Probability Distributions: Further Examples 
    Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    For two families of beta distributions, we show that the generalized Stieltjes transforms of their elements may be written as elementary functions (powers and fractions) of the Stieltjes transform of the Wigner distribution. ...
