Sharp two-parameter bounds for the identric mean [PDF]

open access: yesJournal of Inequalities and Applications, 2018
For t∈[0,1/2] $t\in [0,1/2]$ and s≥1 $s\ge 1$, we consider the two-parameter family of means Qt,s(a,b)=Gs(ta+(1−t)b,(1−t)a+tb)A1−s(a,b), $$ Q_{t,s}(a,b)=G^{s}\bigl(ta+(1-t)b,(1-t)a+tb\bigr)A^{1-s}(a,b), $$ where A and G denote the arithmetic and ...

Some Comparison Inequalities for Generalized Muirhead and Identric Means [PDF]

open access: yesJournal of Inequalities and Applications, 2010
For x,y>0,  a,b∈ℝ, with a+b≠0, the generalized Muirhead mean M(a,b;x,y) with parameters a and b and the identric mean I(x,y) are defined by M(a,b;x,y)=((xayb+xbya)/2)1/(a+b) and I(x,y)=(1/e)(yy/xx)1/(y−x), x ...

Bounds of the Neuman-Sándor Mean Using Power and Identric Means [PDF]

open access: yesAbstract and Applied Analysis, 2013

ON TWO NEW MEANS OF TWO ARGUMENTS III [PDF]

open access: yesПроблемы анализа, 2018
In this paper we establish two sided inequalities for the following two new means X=X(a,b)=Ae^(G/P-1), Y=Y(a,b)=Ge^(L/A-1), where A, G, L and P are the arithmetic, geometric, logarithmic, and Seiffert means, respectively.

Exact inequalities involving power mean, arithmetic mean and identric mean

open access: yesJournal of Numerical Analysis and Approximation Theory, 2011
For \(p\in \mathbb{R}\), the power mean \(M_{p}(a,b)\) of order \(p\), identric mean \(I(a,b)\) and arithmetic mean \(A(a,b)\) of two positive real numbers \(a\) and \(b\) are defined by \begin{equation*} M_{p}(a,b)= \begin{cases} \displaystyle\left(
