# How to get the curly caligraphic font for sigma algebras?

The title pretty much says it all.

Note that I am aware of the caligraphic font (cal, mathcal) which is actually what wikipedia uses too but books on the measure theory usually contain a much fancier font with many loops and I'd like to use it too if possible.

\$\mathscr{A}\$

Thank you. I'll just add for general convenience that in plain one can use "\input scrload" and macro \scr. – Marek Jun 4 '11 at 11:08
