The Schur-convexity of the mean of a convex function [PDF]
Applied Mathematics Letters, 2009 The authors establish the Schur-convexity at the upper and lower limits of the integral for the mean of a convex function. Furthermore, a new proof of the inequality \[ f\bigg(\frac{a+b}{2}\bigg)=H(0) \leq H(t) \leq H(1)= \frac1{b-a}\int^ b_ a f(x)\,dx \] obtained by \textit{S. S. Dragomir} [J. Math. Anal. Appl. 167, No. 1, 49--56 (1992; Zbl 0758.26014)

Characterization of Inner Product Spaces by Strongly Schur-Convex Functions [PDF]
Results in Mathematics, 2020 AbstractInvolving the notion of strongly Schur-convex functions we give a new characterization of inner product spaces among norm spaces. We also present a representation theorem for functions which generate strongly Schur-convex sums.

SCHUR CONVEX FUNCTIONALS: FATOU PROPERTY AND REPRESENTATION
Mathematical Finance, 2010The Fatou property for every Schur convex lower semicontinuous (l.s.c.) functional on a general probability space is established. As a result, the existing quantile representations for Schur convex l.s.c. positively homogeneous convex functionals, established on for either p= 1 or p=∞ and with the requirement of the Fatou property, are generalized for

Partition-Optimization with Schur Convex Sum Objective Functions
SIAM Journal on Discrete Mathematics, 2004Summary: We study optimization problems over partitions of the finite set \(N = {1,\dots, n}\), where each element \(i\) in the partitioned set \(N\) is associated with a real number \(\theta^i\) and the objective associated with a partition \(\pi=(\pi_, \ldots, \pi_p)\) has the form \(F(\pi)=f(\theta_{\pi})\), where \( \theta_{\pi} = (\sum_{i\in{\pi_1}
