Number of orders of $k$-sums of $n$-numbers
Thank you! Can you estimate this number from below? Is it $O(|K|^{2(n-1)})$? |

(1-Lipschitz) + (length-preserving) = isometry
Here it is for high dimensional Euclidean case. cs.elte.hu/geometry/Workshop09/large_r5.pdf |

Using that f is 1-Lipschitz and that [aa′] is a diameter, we get that β must be contained in the interior of α Why? |

Is there a generalized Feuerbach point for an irregular non-Euclidean triangle?
I've found synthetic proof for it to the two dimensional non-Euclidean case. But article is in Russian. mccme.ru/free-books/matpros/mpd.pdf#page=155 |
