| Jan 17, 2023 at 16:13 | comment | added | Iosif Pinelis | This is very nice. I have fixed some typos here. Also, to have $D(u,v)<\min(u,v)$ for all $(u,v)\in(0,1)^2$ for a copula $D$, it is already sufficient (and also necessary) that the support of the distribution corresponding to $D$ contain the points $(1.0)$ and $(0,1)$ (rather than the entire unit square); I am not sure, though, if this observation can simplify the proof; apparently not. | |
