Clark measures for rational inner functions II: general bidegrees and higher dimensions
John T. Anderson, Linus Bergqvist, Kelly Bickel +2
We study Clark measures associated with general two-variable rational inner functions (RIFs) on the bidisk, including those with singularities, and with general -variable ration…
Clark Measures for Rational Inner Functions
Kelly Bickel, Joseph A. Cima, Alan A. Sola
We analyze the fine structure of Clark measures and Clark isometries associated with two-variable rational inner functions on the bidisk. In the degree (n,1) case, we give a comple…
Isometric Equivalence of Isometries on
Joseph A. Cima, Warren R. Wogen
We consider a natural notion of equivalence for bounded linear operators on for We determine which isometries of finite codimension are equivalent. For these isom…
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 $\T_Θ$…
