Matrix limit theorems of Kato type related to positive linear maps and operator means. (arXiv:1810.05476v1 [math.FA])
来源于:arXiv
We obtain limit theorems for $\Phi(A^p)^{1/p}$ and $(A^p\sigma B)^{1/p}$ as
$p\to\infty$ for positive matrices $A,B$, where $\Phi$ is a positive linear map
between matrix algebras (in particular, $\Phi(A)=KAK^*$) and $\sigma$ is an
operator mean (in particular, the weighted geometric mean), which are
considered as certain reciprocal Lie-Trotter formulas and also a generalization
of Kato's limit to the supremum $A\vee B$ with respect to the spectral order. 查看全文>>
