Toeplitz Operators on the Unit Disk with Radial Symbols
As follows, for example, from Theorem 2.8.3, the Toeplitz operator with radial defining symbols a(r), which is continuous at the boundary point 1, has a trivial structure, nothing but a compact perturbation of a scalar operator, T a(r) =a(1)I+K.
