Abstract

We obtain limit theorems for \(\Phi (A^p)^{1/p}\) and \((A^p\sigma B)^{1/p}\) as \(p\rightarrow \infty \) for positive matrices AB, 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.
