报告内容简介: Averaging operations are important in several contexts. A long-standing problem of defining a suitable geometric mean of several positive definite matrices was solved about 10 years ago using ideas from Riemannian geometry. This mean has pleasing geometric and operator-theoretic properties, and is also finding applications in diverse areas like radar data processing, brain mapping, machine learning etc. We will give a brief introduction to the topic.
