I apologize for burdening MO with such a vapid, nonresearch question, but
I have been curious ever since
Suvrit's popular October 2010
<a href="https://mathoverflow.net/questions/44326/">_Most memorable titles_ MO question</a>
if there were any "$E=mc^2$-titles", as I think of them&mdash;how Einstein in retrospect might have entitled his 1905 paper
(instead of
"Zur Elektrodynamik bewegter Körper"!)&mdash;paper/book titles composed entirely of math symbols.

There are two close misses in the responses to that MO question:
Connes et al.'s
<a href="http://arxiv.org/abs/0806.2401">"Fun with $\mathbb{F}_{1}$"</a>,
and Taubes's 
<a href="http://projecteuclid.org/DPubS?service=UI&version=1.0&verb=Display&handle=euclid.jdg/1214425348">"${\rm GR}={\rm SW}$: Counting curves and connections."</a>
The only title entirely composed of math symbols with which I'm familiar is the delightful book _<a href="http://www.math.upenn.edu/~wilf/AeqB.html">A=B</a>_, by Marko Petkovsek, Herbert Wilf, and Doron Zeilberger.
Can you identify others?

Please interpret this question in a weekend-recreational spirit! :-)
