• #### A Toeplitz-like operator with rational matrix symbol having poles on the unit circle: Fredholm properties ﻿

(Springer, 2021)
This paper concerns the analysis of an unbounded Toeplitz-like operator generated by a rational matrix function having poles on the unit circle T. It extends the analysis of such operators generated by scalar rational ...
• #### A Toeplitz-like operator with rational symbol having poles on the unit circle. III. The adjoint ﻿

(Springer, 2019)
This paper contains a further analysis of the Toeplitz-like operators Tω on Hp with rational symbol ω having poles on the unit circle that were previously studied in Groenewald (Oper Theory Adv Appl 271:239–268, ...
• #### Toeplitz-like operators with rational symbol having poles on the unit circle ﻿

(North-West University (South Africa), 2020)
Let Hp be the Hardy space of p-integrable functions on the unit circle T in the complex plane that have an analytic extension to the open unit disk D. Suppose that ω is a rational function with poles on the unit circle. ...
