AbstractWe introduce and examine the notion ofT-Schur convexity which is naturally connected with Schur convexity. As a particular case, we considerT-Wright convex maps which generalize a well-known and intensively investigated class oft-Wright convex functions. We discuss several properties of this class of functions.

The Best Bounds in Gautschi-Kershaw Inequalities [PDF]
By employing the convolution theorem of Laplace transforms, some asymptotic formulas and integral representations of the gamma, psi and polygamma functions, and other analytic techniques, this note provides an alternative proof of a monotonicity and ...

Schur-convexity, Schur geometric and Schur harmonic convexities of dual form of a class symmetric functions [PDF]
By the properties of Schur-convex function, Schur geometrically convex function and Schur harmonically convex function, Schur-convexity, Schur geometric and Schur harmonic con- vexities of the dual form for a class of symmetric functions are simply proved. As an application, several inequalities are obtained, some of which extend the known ones.

The Schur-convexity of the mean of a convex function
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)

Some Remarks on Various Schur Convexity
The aim of this work is to investigate the Schur convexity, Schur geometrically convexity, Schur harmonically convexity and Schur power convexity of some special functions. Some sufficient conditions are obtained to guarantee the above-mentioned properties satisfy. We attain some special inequalities. Also, we obtain some applications of main results.

A Remark on Schur-convexity of the mean of a convex function [PDF]
In this note two remarks have been made about proving convexity and Schu-convexity of the mean of the convex functionm associated with the Hadamard's inequality which is considered in literature [1] and [2].

Schur m-power convexity of generalized geometric Bonferroni mean involving three parameters
In this paper, we study the Schur m-power convexity of the generalized geometric Bonferroni mean involving three parameters. Our result provides a unified generalization to the work that was done recently by Shi and Wu concerning the Schur convexity of ...
