Almost invariant subspaces of shift operators and products of Toeplitz and Hankel operators
Caixing Gu, In Sung Hwang, Hyoung Joon Kim +2
In this paper we formulate the almost invariant subspaces theorems of backward shift operators in terms of the ranges or kernels of product of Toeplitz and Hankel operators. This a…

Matrix Functions of Bounded Type: An Interplay Between Function Theory and Operator Theory
Raúl E. Curto, In Sung Hwang, Woo Young Lee
In this paper, we study matrix functions of bounded type from the viewpoint of describing an interplay between function theory and operator theory. \ We first establish a criterion…
