review text: Summary: We describe the structure of those transformations on certain sets of positive operators which preserve the \(p\)-norm of linear combinations with given nonzero real coefficients. These sets are the collection of all positive \(p\)th Schatten-class operators and the set of its normalized elements. The results of the work generalize, extend, and unify several former theorems.
