| Feb 24, 2018 at 18:15 | comment | added | YCor | @მამუკაჯიბლაძე why do you ask me? rather ask the OP. I mentioned that there are trivial counterexamples, it's enough for me at the moment. | |
| Feb 24, 2018 at 17:39 | comment | added | მამუკა ჯიბლაძე | @YCor Are not they just diffeomorphic to some $\mathbb R^i\times S^j$? | |
| Feb 24, 2018 at 17:08 | comment | added | YCor | @ArunDebray these questions are not smooth deformation retract invariants. $\mathbf{R}^3-\{0\}$ is parallelizable but is SDR to the 2-sphere... | |
