Operator-valued rational functions
Raul E. Curto, In Sung Hwang, Woo Young Lee
In this paper we show that every inner divisor of the operator-valued coordinate function, , is a Blaschke-Potapov factor. We also introduce a notion of operator-valued "rati…
Circle companions of Hardy spaces of the unit disk
Raul E. Curto, In Sung Hwang, Sumin Kim +1
This paper gives a complete answer to the following problem: Find the circle companion of the Hardy space of the unit disk with values in the space of all bounded linear operators…
The Local Operator Moment Problem on
Raul E. Curto, Abderrazzak Ech-charyfy, Hamza El Azhar +1
We study the connections between operator moment sequences of self-adjoint operators on a complex Hilbert space a…
Classes of operators related to subnormal operators
Raúl E. Curto, Thankarajan Prasad
In this paper we attempt to lay the foundations for a theory encompassing some natural extensions of the class of subnormal operators, namely the --subnormal operators and the s…
Signed representing measures (Berger-type charges) in subnormality and related properties of weighted shifts
Chafiq Benhida, Raúl E. Curto, George R. Exner
In the study of the geometrically regular weighted shifts (GRWS) -- see [5] -- signed power representing measures (which we call Berger-type charges) played an important role. Moti…
Geometrically regular weighted shifts
Chafiq Benhida, Raul E. Curto, George R. Exner
We study a general class of weighted shifts whose weights are given by , where and and are parameters so that $(N,D) \in…
