摘要:A model space is a closed subspace of the Hardy space which is invariant under the backward shift, and a truncated Toeplitz operator is the compression of a Toeplitz operator on some model space. In this talk, we discuss necessary and sufficient conditions for the commutator or semicommutator of two truncated Toeplitz operators on a model space to be compact.
