Schur-convexity of the means,
The property of Schur-covexity (Schur-concavity) of means is considered and compared with recent results in the literature [1], [4], [2], [3]. A new proof for convexity (concavity) and Schur- covexity (Schur-concavity) of the integral arithmetic mean is done. We established the sufficient conditions such that the generalized quasi-arithmetic mean Mf (k ; x ; y) and the generalized weighted integral quasi-arithmetic mean Mf (p ; k ; x ; y)are Schur-convex (or concave) with respect to (x ; y). The applications for the extended mean values E(r ; s ; x ; y) and weighted power integral meanM[r](p ; k ; x ; y) are pointed out.References [1] N. Elezovic and J.
