## Abstract:

For $\phi$ in ${H^\infty }$, let ${T_\phi }$ be the analytic Toeplitz operator with symbol $\phi$ and let $\{ {T_\phi }\} ’$ be the commutant of ${T_\phi }$. Two infinite Blaschke products $\phi$ and $\psi$, are exhibited such that $\{ {T_\phi }\} ’ \cap \{ {T_\psi }\} ’$ is not equal to $\{ {T_\theta }\} ’$ for any inner function $\theta$. Also, two questions on reducing subspaces of analytic Toeplitz operators are answered.## References
