Inequalities for means in two variables

H Alzer, S Qiu - Archiv der Mathematik, 2003 - Springer
We present various new inequalities involving the logarithmic mean L(x,y)=(xy)/(xy), the
identric mean I(x,y)=(1/e)(x^x/y^y)^1/(xy), and the classical arithmetic and geometric means …

On the identric and logarithmic means

J Sándor - Aequationes Mathematicae, 1990 - Springer
Let a, b> 0 be positive real numbers. The identric mean I (a, b) of a and b is defined by I= I (a,
b)=(1/e)(bb/aa) 1/(b− a), for a≠ b, I (a, a)= a; while the logarithmic mean L (a, b) of a and b is …

G Jia, J Cao - Journal of Inequalities in Pure and Applied …, 2003 - emis.dsd.sztaki.hu
Proof. Taking t= x 1 12, where x> 1, it is easy to see that inequality (2.4) is equivalent to (2.5)
9 (t4+ 1) 3> 8 (t6+ t3+ 1) 2. Define a function g (t) as g (t)= 9 (t4+ 1) 3− 8 (t6+ t3+ 1) 2 …
