Do you have any idea how to translate the following paper from Frank Esselmann?
- Frank Esselmann, Über die maximale Dimension von Lorentz–Gittern mit coendlicher Spiegelungsgruppe, Journal of Number Theory, Volume 61, Issue 1, November 1996, Pages 103–144.
I didn't find anything good on the Internet. Google trad is quite lame and I tried to fix it by myself but German is pretty hard. Do you have good option to translate this paper? It's quite long: 40 pages.
