Projective Hulls and Characterizations of Meromorphic Functions
J. T. Anderson, J. A. Cima, N. Levenberg +1
We give conditions characterizing holomorphic and meromorphic functions in the unit disk of the complex plane in terms of certain weak forms of the maximum principle. Our work is d…

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 $\T_Θ$…

The Caratheodory-Cartan-Kaup-Wu theorem on an infinite dimensional Hilbert space
Joseph Cima, Ian Graham, Kang-Tae Kim +1
This paper treats a holomorphic self-mapping f: Omega --> Omega of a bounded domain Omega in a separable Hilbert space H with a fixed point p. In case the domain is convex, we prov…
