Several sharp inequalities about the first Seiffert mean [PDF]

open access: yesJournal of Inequalities and Applications, 2018
In this paper, we deal with the problem of finding the best possible bounds for the first Seiffert mean in terms of the geometric combination of logarithmic and the Neuman–Sándor means, and in terms of the geometric combination of logarithmic and the ...

On Seiffert-like means [PDF]

open access: yesJournal of Mathematical Inequalities, 2013
We investigate the representation of homogeneous, symmetric means in the form M(x,y)=\frac{x-y}{2f((x-y)/(x+y))}. This allows for a new approach to comparing means. As an example, we provide optimal estimate of the form (1-\mu)min(x,y)+ \mu max(x,y)

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.

Optimal Two Parameter Bounds for the Seiffert Mean [PDF]

open access: yesJournal of Applied Mathematics, 2013
We obtain sharp bounds for the Seiffert mean in terms of a two parameter family of means. Our results generalize and extend the recent bounds presented in the Journal of Inequalities and Applications (2012) and Abstract and Applied Analysis (2012).

The Optimal Convex Combination Bounds for Seiffert's Mean [PDF]

open access: yesJournal of Inequalities and Applications, 2011
The authors prove the following optimal bounds for the Seiffert mean \(P(a,b)=(a-b)/[2\arcsin ((a-b)/(a+b))]\) by convex combinations of contraharmonic mean \(C(a,b)=(a^{2}+b^{2})/(a+b)\) and geometric mean \(G(a,b)= \sqrt{ab}\), respectively, harmonic mean \(H(a,b)=2ab/(a+b)\). 1) The double inequality \(\alpha _{1}C(a,b)+(1-\alpha _{1})G(a,b)
