Abstract:In this paper, we give a necessary and sufficient condition for the reducibility of a C-0(2) operator by using its characteristic function. Moreover, we obtain the number of reducing subspaces of a C-0(2) operator. As an application, we will restudy the reducibility of the truncated Toeplitz operator A(z)(2) (C) 2019 Elsevier Inc.
