Truncated Toeplitz operators and boundary values in nearly invariant subspaces
Andreas Hartmann, William T. Ross
We consider truncated Toeplitz operator on nearly invariant subspaces of the Hardy space . Of some importance in this context is the boundary behavior of the functions in thes…
Boundary values in range spaces of co-analytic truncated Toeplitz operators
Andreas Hartmann, William T. Ross
Functions in backward shift invariant subspaces have nice analytic continuation properties outside the spectrum of the inner function defining the space. Inside the spectrum of the…
Unitary equivalence to a truncated Toeplitz operator: analytic symbols
Stephan Ramon Garcia, Daniel E. Poore, William T. Ross
Unlike Toeplitz operators on , truncated Toeplitz operators do not have a natural matricial characterization. Consequently, these operators are difficult to study numerically.…
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 and 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 to a model space $\K_Θ := H^2 \ominus ΘH^2$. For inner, let $\T_Θ$…
