weakening the hypothesis
[edit]I think if we replace the phrase
"for all positive real numbers x, y, z and t,"
with
"for all nonnegative real numbers x, y, z and a positive number t,"
, the inequality is still true.
Or any counterexample?
- Yes, you're correct, see Mathematical Excalibur, Vol 10, Number 5, Dec05 to Jan06, online version at http://www.math.ust.hk/mathematical_excalibur/ , further reference at the end of that article(Old and New Inequalities). --Lemontea 01:35, 26 March 2006 (UTC)
I agree - I'm going to update the page.

Applications?
[edit]This article doesn't currently discuss where this inequality is typically used (e.g., what is it useful in proving or modelling?) Dcoetzee 20:56, 28 April 2008 (UTC)
