Abstract:We generalize classical Hobson's formula concerning partial derivatives of radial functions on a Euclidean space to a formula in the Dunkl analysis. As applications we give new simple proofs of known results involving Maxwell's representation of harmonic polynomials, Bochner-Hecke identity, Pizzetti formula for spherical mean, and Rodrigues formula for Hermite polynomials.
“…Pizzetti's formula associated with the Dunkl operators was established by [14,2]. In [21] we proved (3.5) for f ∈ P as an application of Hobson's formula associated with the Dunkl operators. (Note there is an obvious mistake of unnecessary factor (−1) n in [21, Corollary 4.5].)…”

“…Our proof is different from theirs. We also deduce the extended Pizzetti's formula from Pizzetti's formula and Hobson's formula [21].…”

“…We recall Hobson's formula associated with the Dunkl operators. Theorem 3.4 (Hobson's formula [21]).…”
We give an extension of Pizzetti's formula associated with the Dunkl operators. It gives an explicit formula for the Dunkl inner product of an arbitrary function and a homogeneous Dunkl harmonic polynomial on the unit sphere.
