Products of Several Toeplitz Operators

open access: yesJournal of Functional Analysis, 2000
Let \(a\in L^\infty\) and \(T_a:H^2\to H^2\) be a Toeplitz operator with symbol \(a\) acting in Hardy space \(H^2\) on the unit disk. The author describes the necessary and sufficient conditions on symbols \(a_j\) of Toeplitz operators \(T_{a_j}\) when the identity \(T_{a_1}T_{a_2}\dots T_{a_n}=T_{a}\), \(a=a_1a_2\dots a_n\), holds for an arbitrary \(n\

Hankel and Toeplitz Determinants for q-Starlike Functions Involving a q-Analog Integral Operator and q-Exponential Function

open access: yesJournal of Function Spaces
This article investigates the upper bounds of the second Hankel and Toeplitz determinants for a family of q-starlike functions defined by a q-analog integral operator, which is a more general form of the q-Srivastava-Attiya operator, and the q ...

Structured Distance to Normality of Dirichlet–Neumann Tridiagonal Toeplitz Matrices

open access: yesAxioms
This paper conducts a rigorous study on the spectral properties and operator-space distances of perturbed Dirichlet–Neumann tridiagonal (PDNT) Toeplitz matrices, with emphasis on their asymptotic behaviors. We establish explicit closed-form solutions for
