Unitary equivalence to truncated Toeplitz operators

Elizabeth Strouse, Dan Timotin, Mohamed Zarrabi

In this paper we investigate operators unitarily equivalent to truncated Toeplitz operators. We show that this class contains certain sums of tensor products of truncated Toeplitz…

Numerical ranges of $C_{0} (N)$ contractions

Chafiq Benhida, Pamela Gorkin, Dan Timotin

A conjecture of Halmos proved by Choi and Li states that the closure of the numerical range of a contraction on a Hilbert space is the intersection of the closure of the numerical…

Embedding Theorems for Müntz spaces

Isabelle Chalendar, Emmanuel Fricain, Dan Timotin

We discuss boundedness and compactness properties of the embedding $M_{Λ}^{1} \subset L^{1} (μ)$ , where $M_{Λ}^{1}$ is the closure of the monomials $x^{λ_{n}}$ in $L 1 ([0, 1])$ and $μ$ is a finite…
