Generalizing Steinitz's theorem
Obviously a replacement for convexity would be required. The point is to define a geometrically defined object, which would of course have a donut hole, whose graph is precisely genus 1 with vertex connectivity at least 3 (ie, 3-connected.) |

Trichotomies in mathematics
Primes of the form 4n+1, of the form 4n+3, and 2 Primes over a prime p which are unramifed, tamely ramified, or wildly ramified |

Which popular games are the most mathematical?
The rules of chess evolved so as to produce an interesting game. Nonetheless, rigorous theorems and proofs are possible in endgame theory, and anything with proofs of important facts would seem to be mathematical by definition. I think the OP should have said, mathematical but where the mathematics is not well-motivated from a pure math point of view. |

Consecutive integers with no large prime factors
Why would a Norwegian spell his name like a German? Anyway, he didn't. Here's a bio in Norwegian: snl.no/.nbl_biografi/Carl_St%C3%B8rmer/utdypning and another: web.archive.org/web/20080505005456/http://www.fys.uio.no/plasma/… Even so, Viggo Brun spelled the name with an umlaut when writing about him in English. |

The function $\sum_{0}^{\infty} x^n/n^n$
Your observation converts this into a research problem--to characterize Majer sequences, where a Majer sequence is a sequence of positive terms such that $\sum s_n x^n$ is entire and is asymptotic to the x-axis as $x \rightarrow -\infty$. As you note, not any superficially similar sequence will do, by any means--a good example to consider is BesselI(0, 2 sqrt(x)), which has $s_n = 1/(n!)^2$. It seems likely we would need to start from the functions themselves instead of trying to characterize the property in terms of sequences, but one wonders. |
