RE: Motion 52: final "Expressions" text for vote
For intervals proper, the defiition is the same always, f([x1],...,[xn]) is the smallest interval that contains the range of the given function f(x1,...,xn) on given intervals [x1], ..., [xn], i.e., the set of all the values
{f(x1,...,xn):x1 is in [x1], ..., xn is in [xn]}.
The questions arise when we want to extend this to situations when [xi] are not intervals
(there are also definitions for decorations)

Vladik,
Then please point me to the purely mathematical foundation for computing
with "well defined" intervals.
Cheers,
