The sentence A simply connected space and a simple space are the examples of nilpotent spaces is ambigous. Are these two classes the only possible examples of a nilpotent space by some theorem (in which case a citation to the theorem is in order)? Or are they motivating examples, or typical examples, or untypical examples, or elementary examples, or foundational examples? Or should the sentence simply read "... are examples..."?

Right, that was a grammatical error; "the" shouldn't be there. I edited it according. (Thank you for spotting it.) -- Taku ( talk) 12:50, 10 March 2014 (UTC) reply
