Best Hölder exponents of surjective maps from the unit square to the unit cube
I can believe that it might follow from the main theorem of that paper, but I don't see that it follows immediately! I am a bit rusty - maybe I am missing a well-known fact about maps between cubes in $\mathbb{R}^n$? The theorem in the paper does not talk about surjective maps - although in the case of maps to the interval, surjectivity is obvious, I can imagine that this need not be the case in higher dimensions. Can you provide more details of why that theorem implies your claim? |

Do Random Walks on the Hexagonal Lattice have a limit?
The argument about looking at pairs of steps makes this straightforward. |

Did ancient mathematicians know Euler's characteristic for convex polyhedra?
This seems to just assert the received answer 'no' to the question, rather than give any evidence in support of that answer. |

Can one measure the infeasibility of four color proofs?
None of the estimations made in the answer are as flagrantly misguided as assuming that all uses of 'few' refer to a single constant. |
