editThis article reads like an advanced mathematics textbook. However, Wikipedia is an encyclopedia for a general audience, not a textbook. Please see Wikipedia:What_Wikipedia_is_not#Wikipedia_is_not_a_manual,_guidebook,_textbook,_or_scientific_journal. #6 and #8.

- This is an incomplete article on Hadamard spaces and their compactications: Busemann functions are the main device for identifying the boundary (e.g. the Gromov boundary). If wikipedians complain and try to find any useful information on Hadamard spaces, the alternative are vague comments, mostly unreferenced at the level of sub-stub. On the other hand the lede could be better written, emphasising why they are used, and the sections on the unit disk could be completed. Many examples mathematical articles on wikipedia have similar problems. Mathsci (talk) 20:04, 26 July 2020 (UTC)
