Separately Radial and Radial Toeplitz Operators on the Unit Ball and Representation Theory (1509.07063v2)
Published 23 Sep 2015 in math.FA and math.OA
Abstract: We study Toeplitz operators with separately radial and radial symbols on the weighted Bergman spaces on the unit ball. The unitary equivalence of such operators with multiplication operators on $\ell2$ spaces was previously obtained by analytic methods elsewhere (see the references). We prove that the same constructions can be performed with a purely representation theoretic approach to obtain the same conclusions and formulas. However, our method is shorter, more elementary and more elucidating.
