A CONCISE PROOF OF A DOUBLE INEQUALITY INVOLVING
THE EXPONENTIAL AND LOGARITHMIC FUNCTIONS
Huan-Nan Shi,Shan-He Wu
Abstract. In this note we provide a concise proof for a double inequality involving
the exponential and logarithmic functions, our method is based on the usage of the
majorization inequalities and the Schur-convexity of a function.
Keywords: inequality, exponential function, logarithmic function, Schur-convexity,
majorization inequality, Stolarsky mean.
