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
