noticed that the first question is answered

Mar 19, 2010 at 23:25 | comment | added | Ryan Budney | If the boundary is a standard sphere then the contractible manifold has to be the standard disc. This is an h-cobordism theorem type argument -- puncture your contractible manifold, this gives an h-cobordism, etc. | |
Mar 19, 2010 at 23:21 | comment | added | Sergei Ivanov | I see. By the way, are there examples bounded by the standard sphere? | |
