Spatial isomorphisms of algebras of truncated Toeplitz operators

Stephan Ramon Garcia, William T. Ross, Warren R. Wogen

We examine when two maximal abelian algebras in the truncated Toeplitz operators are spatially isomorphic. This builds upon recent work of N. Sedlock, who obtained a complete descr…

The Norm of a Truncated Toeplitz Operator

Stephan Ramon Garcia, William T. Ross

We prove several lower bounds for the norm of a truncated Toeplitz operator and obtain a curious relationship between the $H^{2}$ and $H^{\infty}$ norms of functions in model spaces.

Truncated Toeplitz Operators: Spatial Isomorphism, Unitary Equivalence, and Similarity

Joseph A. Cima, Stephan Ramon Garcia, William T. Ross +1

A truncated Toeplitz operator is the compression $A_ϕ:\K_Θ \to \K_Θ$ of a Toeplitz operator $T_{ϕ} : H^{2} \to H^{2}$ to a model space $\K_Θ := H^2 \ominus ΘH^2$. For $Θ$ inner, let $\T_Θ$…
