# Isoperimetric Area Function

I'm reading the definition of isoperimetric function area and appeared the following notation:

$Ł^{n}_{g}(\Omega)$, where n is dimension of Riemannian manifold $(M,g)$.

What is the meaning of $Ł^{n}_{g}(\Omega)$?

Are you aware that your TeX command \L is not working? Can you add a link, reference, or image of the definition you are reading? –  Rahul Aug 27 '12 at 21:52
Sorry, I use $\L$ WinEdt and works. It's not working here. I do not understand? I'm reading the definition 2.2 on page 4 of this article arxiv.org/pdf/1204.6065.pdf thank you. –  Manoel Aug 28 '12 at 0:30
I may have fixed your $\L$. Let me know if I have chosen the wrong interpretation of what you meant. So you know for next time, I used \mathcal L –  Sam Lisi Aug 28 '12 at 15:05
Sam, this is not what I wanted to write. It's the definition 2.2 of this file arxiv.org/pdf/1204.6065.pdf But thanks for helping. –  Manoel Aug 28 '12 at 16:24
It seems MathJax doesn't support \L for the L with stroke character. I've added the character in directly. –  Rahul Aug 28 '12 at 19:49
