Summary
We prove four theorems characterizing the unweighted power means among all unweighted means. We then build a tool for converting characterization theorems for unweighted means into characterization theorems for weighted theorems. Using this tool, we deduce four theorems characterizing the weighted power means among all weighted means. The main new feature of the theorems proved in this chapter is that they do not assume continuity.
