I think Math.SE may not be the right venue for a simple question I have:
In English, is there any difference between: for all $c>0$ and for any $c>0$ ? I think the later sounds better but not sure. In terms of style, what would be preferable?
If Math.SE is not the right venue for style questions. Is there a good place? I know there is an English site but there it is less likely it will get the attention of professional mathematicians or related.
