The semi-commutator of Toeplitz operators on the bidisc

Caixing Gu, Dechao Zheng

In this paper we characterize when the semi-commutator $T_{f} T_{g} - T_{f g}$ of two Toeplitz operators $T_{f}$ and $T_{g}$ on the Hardy space of the bidisc is zero. We also show that there i…

Products of Block Toeplitz operators

Caixing Gu, Dechao Zheng

In this paper we characterize when the product of two block Toeplitz operators is a compact perturbation of a block Toeplitz operator on the Hardy space of the open unit disk. Nece…
