The semi-commutator of Toeplitz operators on the bidisc
Caixing Gu, Dechao Zheng
In this paper we characterize when the semi-commutator of two Toeplitz operators and 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…
