Abstract
If f is M-harmonic and integrable with respect to a weighted radial measure $\small{\upsilon_{\alpha}}$ over the unit ball $\small{B_n}$ of $\small{\mathbb{C}^n}$, then $\int_{B_n}(f\circ\psi)d\upsilon_{\alpha} Keywords M-harmonic function;weighted Berezin transform;Gelfand transform; Language English Cited by References 1.
