Abstract : 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
