Nov 10, 2017 at 14:55 | comment | added | Ramiro de la Vega | @BjørnKjos-Hanssen: No, it is not the same construction. To see that $|S\cap D|=1$ for $S \in \mathcal S_0$, note that if $d_\xi \in S$ then for each $\alpha>\xi$, $d_\alpha$ was chosen in $X \setminus S$. So $\xi$ is the least index (and hence the only index) for which $d_\xi \in S$. | |
