comment Is there a Fourier transform for principal r-discrete groupoids?
I'm potentially interested in knowing about Fourier transforms on discrete groupoids.

comment Why does bosonic string theory require 26 spacetime dimensions?
Isn't the title also exceedingly uninformative? It should be obvious to mathematicians that a title "Why 26?" must refer to the number of sporadic finite simple groups. I suppose chemists might start wondering about Iron's properties or something.

comment Heuristic argument that finite simple groups _ought_ to be “classifiable”?
Isn't the ultra product of the alternating groups definably simple but not simple? There is a deep result of Boris Zilber's that definable simplicity implies simplicity for groups of finite Morley rank, which suggests those simple groups might be classifiable.

comment Asymptotics of the number of required Dehn relators in hyperbolic groups
I hadn't even considered finite groups, but amusingly the alternating and symmetric groups might be "the easiest example to bear in mind" for my purposes, thanks!
