Binormal block Toeplitz operators with matrix valued circulant symbols
Nihat Gokhan Gogus, Rewayat Khan, Eungil Ko +1
This paper focuses on the binormality of block Toeplitz operators with matrix valued circulant symbols. We also study some Γ-dilations of Toeplitz operators. Moreover, we also anal…
On complex symmetric block Toeplitz operators
Dong-O Kang, Eungil Ko, Ji Eun Lee
In this paper, we study complex symmetry of Toeplitz operators and block Toeplitz operators. In particular, we give a characterization of complex symmetric block Toeplitz operators…
Almost invariant half-spaces for operators on Hilbert space. II: operator matrices
Il Bong Jung, Eungil Ko, Carl Pearcy
This paper is a sequel to [6]. In that paper we transferred the discussions in [1] and [13] concerning almost invariant half-spaces for operators on complex Banach spaces to the co…
Spectra of Some Weighted Composition Operators on
Carl Cowen, Eungil Ko, Derek Thompson +1
We completely characterize the spectrum of a weighted composition operator on when has Denjoy-Wolff point with , the iterates,…
