Özet

We consider the Toeplitz operators on the Bergman space L(a)(2)(D) on the unit disc D. In terms of reproducing kernels the invariant subspaces of Bergman space Toeplitz operator is studied. We also investigate invertibility of Toeplitz operators in terms of Berezin symbols. Moreover, the Hankel operators and Berezin symbols are used to characterize compactness of operators 2T(phi psi) - T(phi)T(psi) - T(psi)T(phi) for bounded harmonic functions phi and psi.
