Abstract:In this note, we give a simple characterization of the chaotic order $\log A \ge \log B$ among positive invertible operators $A, B$ on a Hilbert space. As an application, we discuss Furuta's type operator inequality.

Keywords:Positive operators  chaotic order  L\"{o}wner-Heinz inequality  Furuta inequality
