Matrix Mean: A generalisation of classical means (arithmetic, geometric, harmonic) to matrices, preserving important properties such as congruence invariance.

The arithmetic-geometric-harmonic inequality has played a special role in elementary mathematics. During the past twenty five years (see [1], [2] and [8] etc.) a great many mathematicians have ...
