Algebras of block Toeplitz matrices with commuting entries
Muhammad Ahsan Khan, Dan Timotin
The maximal algebras of scalar Toeplitz matrices are known to be formed by generalized circulants. The identification of algebras consisting of block Toeplitz matrices is a harder…

A Family of Maximal Algebras of Block Toeplitz matrices
Muhammad Ahsan Khan
The maximal commutative subalgebras containing only Toeplitz matrices have been identified as generalized circulants. A similar simple description cannot be obtained for block Toep…
