C*-algebras generated by radial Toeplitz operators on polyanalytic weighted Bergman spaces
Abstract
In a previous paper (Radial operators on polyanalytic weighted Bergman spaces, Bol. Soc. Mat. Mex. 27, 43), using disk polynomials as an orthonormal basis in the -analytic weighted Bergman space, we showed that for every bounded radial generating symbol , the associated Toeplitz operator, acting in this space, can be identified with a matrix sequence , where the entries of the matrices are certain integrals involving and Jacobi polynomials. In this paper, we suppose that the generating symbols have finite limits on the boundary and prove that the C*-algebra generated by the corresponding matrix sequences is the C*-algebra of all matrix sequences having scalar limits at infinity. We use Kaplansky's noncommutative analog of the Stone--Weierstrass theorem and some ideas from several papers by Loaiza, Lozano, Ram\'{i}rez-Ortega, Ram\'{i}rez-Mora, and S\'{a}nchez-Nungaray. We also prove that for , the closure of the set of matrix sequences is not equal to the generated C*-algebra.
