Sharp inequalities between harmonic, Seiffert, quadratic and contraharmonic means
Sharp inequalities between harmonic, Seiffert, quadratic and contraharmonic means
In this paper, we present the greatest values α, λ and p, and the least values β, µ and q such that the double inequalities αD(a, b)a, b) hold for all a, b > 0 with a = b, where H(a, b) = 2ab/(a + b), T (a, b) = …
