Description
For x=(x1,x2,…,xn)∈R+n, the second dual form of the Hamy symmetric function is defined by where r∈{1,2,…,n} and i1,i2,…,in are positive integers. In this paper, we prove that Hn∗∗(x,r) is Schur concave, and Schur multiplicatively and harmonic convex in R+n. Some applications in inequalities and reliability theory are presented.
