Block Toeplitz Operators, Matrix Valued Truncated Toeplitz operators, and Conjugations

Rewayat Khan

In this paper, we characterize the complex symmetry of block Toeplitz operators on the Hardy-Hilbert space H2(E) with conjugation C_{u,λ}, where E is a finite dimensional Hilbert s…

Matrix-Valued Truncated Toeplitz Operators: Properties and Applications

Rewayat Khan, Flavia Colonna

In this paper, we present an application of matrix-valued truncated Toeplitz operators to the matrix version of the Nevanlinna-Pick interpolation problem. We then investigate the u…

On matrix valued (asymmetric) truncated Toeplitz operators

Nihat Gokhan Gogus, Rewayat Khan

Matrix valued (asymmetric) truncated Toeplitz operators are generally not complex symmetric. In this paper, we define a new conjugation with unique properties and study its relatio…

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…

Rigorous Perturbation Bounds for the QX Decomposition for Centrosymmetric Matrices

Aamir Farooq, Rewayat Khan, Uzma Rani +1

Konrad Burnik suggests a structure-preserving QR factorization for centrosymmetric matrices, known as QX factorization. In this article, we obtain the explicit expressions for rigo…

Characterizations of Matrix Valued Asymmetric Truncated Toeplitz Operators

Rewayat Khan, Yagoub Ameur, Jamroz Khan

We characterize matrix-valued asymmetric truncated Toeplitz operators (which are compressions of multiplication operators acting between two possibly different model spaces) by usi…

Matrix valued truncated Toeplitz operators: basic properties

Rewayat Khan, Dan Timotin

Matrix valued truncated Toeplitz operators act on vector-valued model spaces. They represent a generalization of block Toeplitz matrices. A characterization of these operators anal…
