Operator means deformed by a fixed point method

Functional Analysis 2017-11-29 v1

Abstract

By means of a fixed point method we discuss the deformation of operator means and multivariate means of positive definite matrices/operators. It is shown that the deformation of an operator mean becomes again an operator mean. The means deformed by the weighted power means are particularly examined.
