| Jun 13, 2012 at 21:02 | comment | added | Patricia Hersh | Sergey, thank you for yet another helpful answer to one of my questions!! I imagine that (hopefully) once I study these examples enough, I should be able to answer for myself the above question about what sort of neighborhood will be homeomorphic to ${\mathbb R}^5$. Unlike in my earlier question, I plan to wait like a week this time before accepting any answer as "the answer", just in case people here do have different ways of thinking about this. | |
