Abstract |
|
We characterize the closed operators with domain contained in the Hardy space H2 that commute with the backward shift. Also, we give necessary and sufficient conditions for such an operator to be a Toeplitz operator with symbol the complex conjugate of a function in H2. In particular, we show that this fact depends only on the domain. |
