Is this what you meant to write?

Anyway, if you're looking for functions on that are uniformly continuous and such that their product is not, you won't find any. Indeed, on a segment, uniformly continuous is equivalent to continuous (this is called Heine Theorem (at least in France)), and the product of two continuous functions is continuous. - Oct 20th 2008, 01:51 PMszpengchaowrong
