Abstract:
The study of operator means is a substantial subarea in operator theory. Those means can apparently be viewed as operations on positive (definite/semidefinite) cones in operator algebras.
In this talk, we survey results concerning the corresponding isomorphisms between such cones. We will mainly consider Kubo-Ando means, but besides them, we deal also with other types of operator means such as the Fiedler-Ptak spectral geometric mean, the Wasserstein mean... A recent related result concerning the preservers of Tsallis operator relative entropies will be presented, too.
