Some properties of unbounded truncated Toeplitz operators
Ali Chettih, Ameur Yagoub, Zohra Bendaoud
In this paper, we study closed densely defined unbounded truncated Toeplitz operators on model space, where u is an inner function, that commute with modified compressed shifts. Th…
Product of rectangular Toeplitz (Hankel) matrices
Said Bensliman, Ameur Yagoub, Kamel Toumache
In this paper, we study products of asymmetric Toeplitz matrices, we give necessary and sufficient conditions for the product of two asymmetric Toeplitz matrices compatible sizes i…
On Some Algebraic Properties of Block Toeplitz Matrices with Commuting Entries
Muhammad Ahsan Khan, Ameur Yagoub
Toeplitz matrices are ubiquitous and play important roles across many areas of mathematics. In this paper, we present some algebraic results concerning block Toeplitz matrices with…
On some algebras of truncated Hankel and asymmetric truncated Hankel operators
Ameur Yagoub, Muhammad Ahsan Khan
In the last decade, a large amount of research has been concentrated on the operators living on the model space. Asymmetric truncated Toeplitz operators and asymmetric truncated Ha…
