| Jul 22, 2014 at 16:08 | comment | added | bentspoon | @Hwang Thanks for your response. I don't have a copy of Introduction to Symplectic Topology, and I couldn't find a .pdf online, but are you sure that it is stated there that this question is not known? Note that the question does not ask for a $\delta > 0$ such that any two $B(\delta)$ are isotopic, which is known to be not known; rather, the question asks about subballs of two fixed balls, which I think should be easier. | |
| Jul 22, 2014 at 9:16 | comment | added | Hwang | According to "Introduction to Symplectic Topology" by McDuff and Salamon, it is not known. See Section "Blowing up and down". I don't know what was done after the book was written. | |
