Hermitian semidefinite matrix means and related matrix inequalities. An introduction. (English) Zbl 0548.15013
This attractive survey article summarizes recent work on matrix valued inequalities arising from electrical network theory. The means in question are chiefly the arithmetic, geometric, and harmonic, but in matrix dress. There is a bibliography of 32 items, many quite recent. The nontechnical and easy to read character of the article should draw attention to the topic it discusses.
