We give an extension of Pizzetti’s formula associated with the Dunkl operators. It gives explicit for inner product arbitrary function and a homogeneous harmonic polynomial on unit sphere.

Dunkl operators are differential-difference operators on R which generalize partial derivatives. They lead to generalizations of Laplace operators, Fourier transforms, heat semigroups, Hermite polynomials, and so on. In this paper we introduce two systems of biorthogonal polynomials with respect to Dunkl’s Gaussian distributions in a quite canonical way. These systems, called Appell systems, ad...
Abstract. We give shorter proofs of the following known results: the radial Dunkl process associated with a reduced system and a strictly positive multiplicity function is the unique strong solution for all times t of a stochastic differential equation with a singular drift (see [11] for the original proof and [4] for a proof under an additional restriction), the first hitting time of the Weyl ...
In this paper, we construct a linear positive operators q-parametric Szász Mirakjan operators generated by the q-Dunkl generalization of the exponential function. We obtain Korovkin’s type approximation theorem for these operators and compute convergence of these operators by using the modulus of continuity. Furthermore, the rate of convergence of the operators for functions belonging to the Li...
For a locally compact Hausdorff semigroup S, the L representation algebra R(S) was extensively studied by Dunkl and Ramirez. The FourierStieltjes algebra F (S) of a topological semigroup was studied by Lau. The aim of this paper is to investigate these two algebras and study the amenability of them with respect to the structure of S.
This paper is intented to establish the analogue of Titchmarsh?s theorem for Dunkl generalized transform on real line.
