Talk:Poincaré inequality

This page will be expanded. In particular, there will be other forms of the inequalitie too.

But is it "inequality" or "inequalitie"? --Boris Tsirelson (talk) 20:33, 26 November 2012 (CET)

Also, what is $f_B$? --Boris Tsirelson (talk) 20:39, 26 November 2012 (CET)

It is "inequality", I am sorry for such a typo. Is there a mechanism to change the name of this page? The constant $f_B$ is average value over ball $B$, I added this --Nikita2 (talk) 04:47, 27 November 2012 (CET)
