On the Monotonicity and Log-Convexity of a Four-Parameter Homogeneous Mean

Open Access
Research Article

Abstract

A four-parameter homogeneous mean Open image in new window is defined by another approach. The criterion of its monotonicity and logarithmically convexity is presented, and three refined chains of inequalities for two-parameter mean values are deduced which contain many new and classical inequalities for means.
