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
How about Section E here? (Citation: Joyce, W. B. (1974). Classical-particle description of photons and phonons. Physical Review D, 9 (12), 3234.) |

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. |

Texts about Dwork's work
Certainly check out Koblitz's book (if you haven't already) entitled, "p-adic Numbers, p-adic Analysis, and Zeta-Functions" as mentioned here... |
