Unitary equivalence to a truncated Toeplitz operator: analytic symbols [PDF]

open access: yes, 2011
Unlike Toeplitz operators on $H^2$, truncated Toeplitz operators do not have a natural matricial characterization. Consequently, these operators are difficult to study numerically.

Reducing Subspaces of the Dual Truncated Toeplitz Operator

open access: yesJournal of Function Spaces, 2018
We define the dual truncated Toeplitz operators and give some basic properties of them. In particular, spectrum and reducing subspaces of some special dual truncated Toeplitz operator are characterized.

Toeplitz Operators on Weighted Bergman Spaces [PDF]

open access: yesJournal of Function Spaces and Applications, 2013
We characterize the boundedness and compactness of a Toeplitz-type operator on weighted Bergman spaces satisfying the Bekollé-Bonami condition in terms of the Berezin transform.

Online Spatiotemporally Constrained Reconstruction for Real-Time Interactive MRI. [PDF]

open access: yesMagn Reson Med
ABSTRACT Purpose To develop a low‐latency dynamic MRI reconstruction that provides better spatial and temporal fidelity than contemporary online reconstruction, for localization. Methods We utilize online spatiotemporally constrained reconstruction (STCR) using a computationally efficient augmented Lagrangian solution and a limited number of iterations

On a weighted Toeplitz operator and its commutant

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We study the structure of a class of weighted Toeplitz operators and obtain a description of the commutant of each operator in this class. We make some progress towards proving that the only operator in the commutant which is not a scalar multiple of the

Toeplitz operators and Wiener-Hopf factorisation: an introduction

open access: yesConcrete Operators, 2017
Wiener-Hopf factorisation plays an important role in the theory of Toeplitz operators. We consider here Toeplitz operators in the Hardy spaces Hp of the upper half-plane and we review how their Fredholm properties can be studied in terms of a Wiener-Hopf
