The log-convexity of another class of one-parameter means and its applications
Zhen-Hang Yang
Zhejiang Province Electric Power Test and Research Institute
In this paper, the log-convexity of another class one-parameter mean is investigated. As applications, some new upper and lower bounds of logarithmic mean, new estimations for identric mean and new inequalities for power-exponential mean and exponential-geometric mean are first given.
Keywords: Stolarsky mean, Gini mean, one-parameter homogeneous functions, log-convexity, inequality
