On preservers related to the spectral geometric mean
In this paper we study preserver transformations between positive definite cones in operator algebras relating the spectral geometric mean of Fiedler and Pták. We also discuss kinds of structural similarities and dissimilarities between the Kubo-Ando geometric mean and the spectral geometric mean. ©...
