Complex symmetric partial isometries
Stephan Ramon Garcia, Warren R. Wogen
An operator $T \in B(\h)$ is complex symmetric if there exists a conjugate-linear, isometric involution $C:\h\to\h$ so that . We provide a concrete description of all co…
Some new classes of complex symmetric operators
Stephan Ramon Garcia, Warren R. Wogen
We say that an operator is complex symmetric if there exists a conjugate-linear, isometric involution so that . We prove that binormal operators,…
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 $\T_Θ$…
Norm estimates of complex symmetric operators applied to quantum systems
Emil Prodan, Stephan R. Garcia, Mihai Putinar
This paper communicates recent results in theory of complex symmetric operators and shows, through two non-trivial examples, their potential usefulness in the study of Schrödinger…
