Convexity for ratio of difference of some special means in two variables

In this paper, we study the Schur properties of convexities(concave) like Schur, Schur Geometric, Schur Harmonic convexities on the ratio of difference of means obtained by arithmetic mean, geometric mean, harmonic mean, contra harmonic mean, heron mean and root-square means. Also, established some inequalities related to these means.
