| Nov 29, 2012 at 4:09 | comment | added | Will Sawin | You cannot take $y$ to be in $x_i$. Just take two independent points on an elliptic curve. | |
| Nov 29, 2012 at 1:07 | comment | added | prochet | yes. Or even, can we take $y$ is one of the $x_{i}$ | |
| Nov 29, 2012 at 0:42 | comment | added | Will Sawin | When is $y$ chosen? | |
| Nov 29, 2012 at 0:16 | comment | added | prochet | Thanks, and if I allow two poles? Say I add one point $y$ to the d-uple. Can we have $k[t_{i}^{-1}]\subset k[X-\{y,x_{i}\}]$? | |
