报告摘要：

We recall the background of operator mean concentrated on geometric means. We study the metric geometric mean and two kinds of spectral geometric means with their similarity and difference. We finally see the recent results on quantum divergence, as matrix versions of the squared Hellinger distance, and barycenter to minimize quantum divergences.
