# Spectra for Toeplitz Operators Associated with a Constrained Subalgebra

@inproceedings{Felder2021SpectraFT, title={Spectra for Toeplitz Operators Associated with a Constrained Subalgebra}, author={Christopher Felder and Douglas T. Pfeffer and Benjamin P. Russo}, year={2021} }

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.
