Schur m-Power Convexity of a Class of Multiplicatively Convex Functions and Applications
We investigate the conditions under which the symmetric functions Fn,k(x,r)=∏1≤i1<i2<⋯<ik≤n f(∑j=1kxijr)1/r, k=1,2,…,n, are Schur m-power convex for x∈R++n and r>0. As a consequence, we prove that these functions are Schur geometrically convex and Schur harmonically convex, which gene...
