Solution of the Reconstruction-of-the-Measure Problem for Canonical Invariant Subspaces

Raul E. Curto, Sang Hoon Lee, Jasang Yoon

We study the Reconstruction-of-the-Measure Problem (ROMP) for commuting 2-variable weighted shifts $W_{(α, β)}$ , when the initial data are given as the Berger measure of the restric…

Polynomial embeddings of unilateral weighted shifts into $2$ -variable weighted shifts

Raul E. Curto, Sang Hoon Lee, Jasang Yoon

Given a bounded sequence ωof positive numbers and its associated unilateral weighted shift W_ω acting on the Hilbert space \ell^2(\mathbb{Z}_+), we consider natural representations…

The Spectral Picture and Joint Spectral Radius of the Generalized Spherical Aluthge Transform

Chafiq Benhida, Raul E. Curto, Sang Hoon Lee +1

For an arbitrary commuting $d$ --tuple $\bT$ of Hilbert space operators, we fully determine the spectral picture of the generalized spherical Aluthge transform $\dbT$ and we prove t…
