PROPERTIES OF DUAL TOEPLITZ OPERATORS WITH APPLICATIONS TO HAPLITZ PRODUCTS ON THE HARDY SPACE OF THE POLYDISK [PDF]
Taiwanese Journal of Mathematics, 2015 In this paper, we introduce dual Toeplitz operators on the orthogonal complement of the Hardy space of the polydisk and establish their main algebraic properties using an auxiliary transformation of operators. As a byproduct, we exploit this mysterious transformation in the investigation of boundedness and compactness of Hankel products and mixed ...

Toeplitz Operators on the Symmetrized Bidisc [PDF]
, 2020 The symmetrized bidisc has been a rich field of holomorphic function theory and operator theory. A certain well-known reproducing kernel Hilbert space of holomorphic functions on the symmetrized bidisc resembles the Hardy space of the unit disc in ...

Algebraic and spectral properties of dual Toeplitz operators [PDF]
Transactions of the American Mathematical Society, 2002 Dual Toeplitz operators are defined on the orthogonal complement of the Bergman space \(L^2_a\) of the disk into \(L^2\) to be multiplication operators followed by projection onto the orthogonal complement. Several algebraic, analytic and spectral properties of dual Toeplitz operators are studied in this nice paper.

Multidimensional Toeplitz and Truncated Toeplitz Operators [PDF]
, 2021 In this thesis we extend previous studies of Toeplitz and truncated Toeplitz operators by studying both Toeplitz and truncated Toeplitz operators with matrix symbols.

A theorem of Brown–Halmos type for dual truncated Toeplitz operators
Annals of Functional Analysis, 2020 The paper proves necessary and sufficient conditions for the commutativity of the product of two dual truncated Toeplitz operators for the unit disk. A truncated dual Toeplitz operator \(D_f\) is defined as \(x\in (K_u^2)^\perp\mapsto D_f\,x=(I-P_u)(fx)\in (K_u^2)^\perp\) where \(K_u^2=H^2\ominus u H^2\) with \(u\) a nonconstant inner function and ...

Weighted Banach spaces of analytic functions with sup-norms and operators between them: a survey [PDF]
, 2022 [EN] In this survey we report about recent work on weighted Banach spaces of analytic functions on the unit disc and on the whole complex plane defined with sup-norms and operators between them.
