Characterizing type I C*-algebras via entropy
Comptes Rendus. Mathématique, Volume 339 (2004) no. 12, pp. 827-829.

Let A be a separable unital C*-algebra. It is shown that A is type I if and only if the CNT-entropy of every inner automorphism of A is zero.

Soit A une C*-algèbre avec unité, séparable, nous montrons que A est de type I si et seulement si la CNT-entropie de tout automorphisme intérieur de A est nulle.
