I apologize for burdening MO with such a vapid, nonresearch question, but
I have been curious ever since
Suvrit's popular October 2010
Most memorable titles MO question
if there were any "$E=mc^2$-titles," as I think of them—how Einstein in retrospect might have entitled his 1905 paper
(instead of
"Zur Elektrodynamik bewegter Körper"!)—paper/book titles composed entirely of math symbols.
There are two close misses in the responses to that MO question:
Connes et al.'s
"Fun with $\mathbb{F}_{1}$",
and Taubes's
"${\rm GR}={\rm SW}$: Counting curves and connections."
The only title entirely composed of math symbols with which I'm familiar is the delightful book A=B, by Marko Petkovsek, Herbert Wilf, and Doron Zeilberger.
Can you identify others?
Please interpret this question in a weekend-recreational spirit! 🙂
