Abstract.Motivated by Hayashi's mapping and characterization of $r$-mean [3], we present a generalization of the mapping and the $\beta $-power-mean which was originated in [4]. Instead of two operators we generalize the $\beta $-power-mean to $2n+1$ operators. Some applications are given about the Furuta-type operator inequalities.

Dedicated to Professor Showhwa Lin
with admiration and respects.
