Abstract:We analyze four bounding schemes for multilinear functions and theoretically compare their tightness. We prove that one of the four schemes provides the convex envelope and that two schemes provide the concave envelope for the product of p variables over 
$$mathbb{R}_{^ + }^p $$
.
Keywords:Convex envelopes  Multiplicative programs  Arithmetic intervals
