Sharp bounds for Neuman means with applications.

In the article, we present the sharp bounds for the Neuman mean NAG(a; b), NGA(a; b), NQA(a; b) and NAQ(a; b) in terms of the convex combinations of the arithmetic and one-parameter harmonic and contraharmonic means. As applications, we find several sharp inequalities for the first Seiffert, second Seiffert, Neuman-Sándor and logarithmic means. [ABSTRACT FROM AUTHOR]
