A new approach to mutual information

Fumio Hiai, Dénes Petz (2007)

Banach Center Publications

Similarity:

A new expression as a certain asymptotic limit via "discrete micro-states" of permutations is provided for the mutual information of both continuous and discrete random variables.

Quantum dynamical entropy revisited

Thomas Hudetz (1998)

Banach Center Publications

Similarity:

We define a new quantum dynamical entropy for a C*-algebra automorphism with an invariant state (and for an appropriate 'approximating' subalgebra), which entropy is a 'hybrid' of the two alternative definitions by Connes, Narnhofer and Thirring resp. by Alicki and Fannes (and earlier, Lindblad). We report on this entropy's properties and on three examples.
