| Feb 18, 2016 at 22:25 | comment | added | user45397 | @JasonStarr Is there any text or literature which deals with a similar question? | |
| Feb 18, 2016 at 22:03 | comment | added | user45397 | @JasonStarr Is there any condition we can add on $\pi$ (not properness) which will ensure one of them? | |
