could max be replaced by sup? 71.225.92.12 02:44, 29 October 2007 (UTC)

I don't believe so. One of the ideas behind Envelope theorem is the explanation of how a maximum changes as those parameters that characterize it change. Perhaps subtly, this is different than a supremum. max entails finding that value of x in the domain which maximizes the objective function subject to a constraint, whereas sup would entail finding the least upper bound of a set (although some envelope theorem problems could likely be restated in terms of finding the sup of a subset of the domain, but this would be quite a different formulation). In this article, max is used correctly Bsdlite (talk) 04:50, 29 May 2008 (UTC)

[edit] Explain "envelope"

A sensible addition, I think, would be an explanation of what this theorem has to do with an "envelope" of functions (ie, explain the name). TBH, I have only a vague understanding of this, so I haven't made a stab.
