-decomposability of positive maps
Wladyslaw A. Majewski, Marcin Marciniak
The problem of classification of decomposable (in the sense of Stormer) positive maps between matrix algebras is presented. We propose the new notion of "finite" version of decompo…
Positive maps, states, entanglement and all that; some old and new problems
Wladyslaw Adam Majewski
We outline a new approach to the characterization as well as to the classification of positive maps. This approach is based on the facial structures of the set of states and of the…
On positive maps, entanglement and quantization
W. A. Majewski
We outline the scheme for quantization of classical Banach space results associated with some prototypes of dynamical maps and describe the quantization of correlations as well. A…
Implementability of Liouville evolution, Koopman and Banach-Lamperti theorems in Classical and Quantum dynamics
I. Antoniou, W. A. Majewski, Z. Suchanecki
We extend the concept of implementability of semigroups of evolution operators associated with dynamical systems to quantum case. We show that such an extension can be properly for…
Quantum recurrences versus stability
Louis L. Labuschagne, Wladyslaw A. Majewski
Consequences of quantum recurrences on the stability of a broad class of dynamical systems is presented.
Does quantum chaos exist? (A quantum Lyapunov exponents approach.)
W. A. Majewski
We shortly review the progress in the domain of deterministic chaos for quantum dynamical systems. With the appropriately extended definition of quantum Lyapunov exponent we analyz…
