Talk:Suslin's problem

How could he pose the problem in early 1920s? Acording to his biography he died in 1919. Glivi 17:58, 27 March 2007 (UTC)
 * Well, a real mathematician doesn't let a little thing like death get in the way of his research. But if you can get more reliable dates, either for this article or the bio (or both), that would be a welcome addition. --Trovatore 00:57, 28 March 2007 (UTC)

Completeness of order
At present we have 'the order on R is complete, in the sense that every non-empty bounded subset has a supremum and an infimum;'. This does not state that a non-empty subset bounded above (but not below) has a supremum, and likewise for infimum. This is to my knowledge the definition of completeness with the reals.

 * Well, the two formulations are easily equivalent, so I doubt we really need to say anything about that. --Trovatore (talk) 15:31, 25 October 2019 (UTC)
