Webwhile the graph convex hull bounds do not require any continuity assumptions. The graph convex hull bounds are obtained by exploiting the basic fact that the mean of the pair (X;f(X)) lies in the closure Conv(G(f)) of the convex hull of the graph G(f) of f, cf. Corollary 3.3andFigure 3.1below, and the proof is a simple application of the Hahn ... Webalso ordered from left to right.
