Semi-Commutators of Toeplitz Operators on Ap(ψ) |

Abstract: | In this paper, we investigate the semi-commutators of Toeplitz operators on the weighted Bergman spaces Ap(ψ), and characterize the bounded harmonic functions u and v on the unit disk for which the semi-commutator of Toeplitz operators Tu and Tv is 0 or compact operator. |
