Properly reference Abbott.

| Dec 30, 2020 at 21:42 | comment | added | Firestone | Thanks again for pusuing this! Google's exiguous snippets give us the phrase, and even an indication that it means the kind of thing I'm interested in, but, alas, no suggestion of the crucial preservation of straightness. So the book is needed. WorldCat finds 5 copies, all (unlike me) in Europe, 2 of them in Paris libraries: at Sorbonne Université, and at Bibliothèque Interuniv Science Jussieu-RCON. If you should happen to visit one of those... Well, perhaps when times are better. | |

Add link to Spanish language Wikipedia page, which has a reference.

| Dec 29, 2020 at 15:49 | comment | added | Firestone | Thank you for the references. Unfortunately, the Wikipedia article cites no sources. Hjelmslev's 1907 paper does not address the application of his theorem to non-Euclidean geometry. Without further information, there is no reason to attribute that application to him. | |
