On mean-value properties for the Dunkl polyharmonic functions
Abstract. We derive differential relations between the Dunkl spherical and solid means of continuous functions. Next we use the relations to give inductive proofs of mean-value properties for the Dunkl polyharmonic functions and their converses.
Keywords: Dunkl Laplacian, Dunkl polyharmonic functions, mean-values, Pizzetti formula.
