Description
Summary:<p/> <p>For <inline-formula> <graphic file="1029-242X-2010-543250-i1.gif"/></inline-formula> and <inline-formula> <graphic file="1029-242X-2010-543250-i2.gif"/></inline-formula>, the symmetric function <inline-formula> <graphic file="1029-242X-2010-543250-i3.gif"/></inline-formula> is defined as <inline-formula> <graphic file="1029-242X-2010-543250-i4.gif"/></inline-formula>, where <inline-formula> <graphic file="1029-242X-2010-543250-i5.gif"/></inline-formula> are positive integers. In this paper, the Schur convexity, Schur multiplicative convexity, and Schur harmonic convexity of <inline-formula> <graphic file="1029-242X-2010-543250-i6.gif"/></inline-formula> are discussed. As consequences, several inequalities are established by use of the theory of majorization.</p>
