• Schur-convexity
• extended mean values

The Schur-convex and Schur-concave properties with (x, y) in (0, infinity) x (0, infinity) for fixed (r, s) of the extended mean values E(r, s; x, y) are researched again, some errors in [F. Qi, J. Sandor, S. S. Dragomir, and A. Sofo, Notes on the Schur-convexity of the extended mean values, Taiwanese J. Math. 9, (3) (2005), 411-420. RGMIA Res. Rep. Coll. 5 (2002), no. 1, Art. 3, 19-27.
