Scribe notes from February 17, 2012

Hi all,

Here are the scribe notes from Feb 17, 2012. (TeX code is available here.) In class, two notations for \( \mathcal{M} \) were given: one without tilde and the other with tilde. The tilde notation works well for simple symbols such as \( \tilde{b} \), \( \tilde{c} \), and \( \tilde{t} \). But, I think, it is not for long terms such as  \( \widetilde{f(t_{1},\ldots,t_{k})} \)   (\widetilde{f(t_{1},\ldots,t_{k})}) . 

Have a great weekend!

Best regards,
Tomoya Sato
