Compactness of products of block Hankel and Toeplitz operators
Caixing Gu, Meng Li, Pan Ma
Motivated by the Sarason problem on the products of Hankel and Toeplitz operators on analytic function spaces, we characterize the compactness of products of block Hankel and Toepl…

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…
