Spectra for Toeplitz Operators Associated with a Constrained Subalgebra

  title={Spectra for Toeplitz Operators Associated with a Constrained Subalgebra},
  author={Christopher Felder and Douglas T. Pfeffer and Benjamin P. Russo},
A two-point algebra is a set of bounded analytic functions on the unit disk that agree at two distinct points a, b ∈ D. This algebra serves as a multiplier algebra for the family of Hardy Hilbert spaces H t := {f ∈ H 2 : f(a) = tf(b)}, where t ∈ C ∪ {∞}. We show that various spectra of certain Toeplitz operators acting on these spaces are connected. 


Eigenvalues of Toeplitz Operators on the Annulus and Neil Algebra
By working with all collection of all the Sarason Hilbert Hardy spaces for the annulus algebra an improvement to the results of Aryana and Clancey on eigenvalues of self-adjoint Toeplitz operators on
Convexity of the Berezin Range
This paper discusses the convexity of the range of the Berezin transform. For a bounded operator T acting on a reproducing kernel Hilbert space H (on a set X), this is the set B(T ) := {〈T k̂x, k̂x〉H
Szegő and Widom Theorems for Finite Codimensional Subalgebras of a Class of Uniform Algebras
We establish versions of Szeg\H{o}'s distance formula and Widom's theorem on invertibility of (a family of) Toeplitz operators in a class of finite codimension subalgebras of uniform algebras,
Szegő and Widom Theorems for the Neil Algebra
Versions of well-known function theoretic operator theory results of Szegő and Widom are established for the Neil algebra. The Neil algebra is the subalgebra of the algebra of bounded analytic

A Corona Theorem for certain subalgebras of H-(D)
Consider algebras of the form C+BH8(D), where B is a Blaschke product, H(D) denotes the bounded analytic functions on the unit disk, and C denotes the complex numbers. We answer a conjecture of
