The non-selfadjoint approach to the Hao-Ng isomorphism
Elias Katsoulis, Christopher Ramsey
In an earlier work, the authors proposed a non-selfadjoint approach to the Hao-Ng isomorphism problem for the full crossed product, depending on the validity of two conjectures sta…
Residually finite-dimensional operator algebras
Raphaël Clouâtre, Christopher Ramsey
We study non-selfadjoint operator algebras that can be entirely understood via their finite-dimensional representations. In contrast with the elementary matricial description of fi…
An operator-valued Lyapunov theorem
Sarah Plosker, Christopher Ramsey
We generalize Lyapunov's convexity theorem for classical (scalar-valued) measures to quantum (operator-valued) measures. In particular, we show that the range of a nonatomic quantu…
On Operator Valued Measures
Darian McLaren, Sarah Plosker, Christopher Ramsey
We consider positive operator valued measures whose image is the bounded operators acting on an infinite-dimensional Hilbert space, and we relax, when possible, the usual assumptio…
