Why does $d^n \exp(-x-x^{-1})/(dx)^n$ only have $n$ positive real zeroes?
RE: (3) The $\phi_n$ appear - I don't think very helpfully, but do not read German - in an old paper of Raabe here. See II on page 95. |

Minimal number of intersections in a convex $n$-gon?
Maybe check this paper (I do not have access, but the abstract looks somewhat promising). |

Probability that a stick randomly broken in five places can form a tetrahedron
@GerryMyerson Thanks for the link. And a "(Dickman, 2013)" attribution around 3:53! Very nice. |

A new generalisation of Fermat's little theorem?
Does Example 2.2(3) here suffice? |

Anti-Mandelbrot set
@AlexandreEremenko You're welcome! I used antiholomorphic and Mandelbrot to find this particular paper; 'Mandelbar' is a pretty good word... |

Nice applications of Liouville's theorem

Idempotent ideal in ring of continuous functions
Not an answer - truly a comment - but perhaps this can add a shred of context: It is easy to find all the idempotent elements in the ring of continuous functions: the two constant functions, $0$ and $1$ (proof: intermediate value theorem). In a Noetherian ring, every idempotent ideal is generated by an idempotent element; unfortunately, this fact is not of direct use here: the ring of continuous functions is not Noetherian. Hence the question at hand may arise. |

Simultaneously using the real and 2adic norms
Not an answer to your question, but the "lynch pin" you identify leads me to recall the very end of Koblitz's book p-adic Numbers, p-adic Analysis, and Zeta-Functions in which he finishes his write-up of Dwork's Theorem (rationality of the Weil Conjectures) as follows. |

Do rational numbers admit a categorification which respects the following “duality”?
Just to link back: This question also connects, to some extent, with the answer I put up to MESE 7837. |
