Model Theory for Operators Related to Square Roots of Normal Operators

Raul E. Curto, Thankarajan Prasad

In this paper we prove that a square root of a cyclic normal operator is unitarily equivalent to a block multiplication operator on a vector-valued Lebesgue space with a $2$ --norma…

Hyponormal block Toeplitz operators with finite rank self-commutators

Mankunikuzhiyil Abhinand, Raul E. Curto, Thankarajan Prasad

In this paper, we identify a large class of hyponormal block Toeplitz operators whose self-commutators are of finite rank. \ Recall that an operator $T_{φ}$ is hyponormal and $[T_φ^{…

Subnormal block Toeplitz operators

Mankunikuzhiyil Abhinand, Raul E. Curto, In Sung Hwang +2

In this paper we consider the subnormality of block Toeplitz operators $T_{Φ}$ , where $Φ$ is an $n \times n$ matrix-valued function on the unit circle $T$ of the form $$ Φ=QΦ^…
