Operator means for operators with positive definite real part
In this article, we consider operator means for two operators with positive definite real part and geometric mean to extend Drury’s results in Drury (Linear Multilinear Algebra 63:296–301, 2015). We also study specified operators with positive definite real part to show their topological properties...

| Zusammenfassung: | In this article, we consider operator means for two operators with positive definite real part and geometric mean to extend Drury’s results in Drury (Linear Multilinear Algebra 63:296–301, 2015). We also study specified operators with positive definite real part to show their topological properties with respect to Thompson’s metric. |
