I apologize for burdening MO with such a vapid, nonresearch question, butI have been curious ever sinceSuvrit's popular October 2010Most memorable titles MO questionif 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! :-)
