1. Furthermore, for a large class of nonanalytic, noncoanalytic Toeplitz operators which include Toeplitz operators with trigonometric or rational symbols, we prove that those Toeplitz operators are Binormal if …

2. For center manifolds associated with a purely imaginary pair of eigenvalues the following is shown by classical means: although center manifolds may be nonanalytic the corresponding equations on center manifolds may be treated as if they were analytic.
