“…It is well known that the convex (concave) functions have wide applications in pure and applied mathematics , many remarkable properties and inequalities can be found in the literature via the theory of convexity. Recently, a great deal of generalizations, extensions, and variants have been made for convexity, for example, GA-convexity [49], GG-convexity [50], -convexity [51,52], preinvex convexity [53], strong convexity [54][55][56][57], Schur convexity [58][59][60], and others [61][62][63][64][65][66][67].…”
