From quasi-entropy

Petz, Denes

Understand

The subject is the overview of the use of quasi-entropy in finite dimensional spaces.

  • Matrix monotone functions and relative modular operators are used.
  • The origin is the relative entropy and the f-divergence, monotone metrics, covariance and the chi-square-divergence are the most important particular cases.
  • The extension of the monotone metric to two variables is a new concept.
