Let µ α be the Lebesgue plane measure on the unit disk with the radial weight α+1 π (1 − |z| 2 ) α . Denote by A n the space of the n-analytic functions on the unit disk D, square integrable with respect to µ α , and by A (n) the true-n-analytic space defined as A n ∩ A ⊥ n−1 . Extending results of Ramazanov (1999Ramazanov ( , 2002, we find the orthonormal basis of L 2 (D, µ α ) that can be obtained by the orthogonalization of the monomials in z and z. In the polar coordinates, this basis is expressed in terms of Jacobi polynomials. Using this basis, we decompose the von Neumann algebra of radial operators, acting in A n , into the direct sum of some matrix algebras, i.e., radial operators are represented as matrix sequences. Furthermore, we prove that the radial operators, acting in A (n) , are diagonal with respect to the same basis restricted to A (n) . In particular, we provide explicit representations of the Toeplitz operators with bounded radial symbols, acting in A n or in A (n) . Moreover, using ideas by Engliš (1996), we show that the set of the Toeplitz operators with bounded generating symbols is not weakly dense in B(A n ).
