Gelfand transforms and boundary representations of complete Nevanlinna--Pick quotients

Raphaël Clouâtre, Edward J. Timko

The main objects under study are quotients of multiplier algebras of certain complete Nevanlinna--Pick spaces, examples of which include the Drury--Arveson space on the ball and th…

The Taylor joint spectrum and restriction to hyperinvariant subspaces

Edward J. Timko

It is well known that for a single bounded operator on a Hilbert , if is hyperinvariant for , then the spectrum of $A_0|…

Localizable points in the support of a multiplier ideal and spectra of constrained operators

Raphaël Clouâtre, Edward J. Timko

A unitarily invariant, complete Nevanlinna--Pick kernel on the unit ball determines a class of operators on Hilbert space called -contractions. We study those -contractio…

Row contractions annihilated by interpolating vanishing ideals

Raphaël Clouâtre, Edward J. Timko

We study similarity classes of commuting row contractions annihilated by what we call higher order vanishing ideals of interpolating sequences. Our main result exhibits a Jordan-ty…

A classification of -tuples of commuting shifts of finite multiplicity

Edward J Timko

Let denote an -tuple of shifts of finite multiplicity, and denote by the ideal consisting of polynomials in complex variables suc…

On polynomial -tuples of commuting isometries

Edward J. Timko

We extend some of the results of Agler, Knese, and McCarthy [1] to -tuples of commuting isometries for . Let be an -tuple of a commuting iso…
