Schur multipliers and operator-valued Foguel-Hankel operators
Catalin Badea, Vern I. Paulsen
Abstract
We show that some matrices are Schur multipliers and this is applied to obtain classes of operator-valued Foguel-Hankel operators similar to contractions. This provides partial answers to a problem of K. Davidson and the second author concerning CAR-valued Foguel-Hankel operators.
