We investigate algebraic structure for the BN -type Calogero model by using the exchange-operator formalism. We show that the set of the Jack polynomials whose arguments are Dunkl-type operators provides an orthogonal basis.

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.

Abstract Some examples of Appell–Dunkl sequences are shown using determined operators. Specifically, whose generating functions the form $$E_{\alpha }(xt)/(1\pm t^m)$$ E α ( x t ) /</...
