| Feb 10, 2010 at 14:45 | comment | added | Daniel Moskovich | I believe (based on a conversation with Sylvain Cappell) that the answer to (2) is no. | |
| Feb 10, 2010 at 6:53 | comment | added | Ryan Budney | I added a few more tags. Regarding (2) hopefully someone like Ruberman will enter the conversation. I don't know any interesting ways of generating knots that I know to be slice but for which I have reason to suspect they maybe aren't ribbon. IMO the smooth Poincare conjecture is in the same situation. We appear to have a deficit of good ways to identify the standard smooth $S^4$. | |
