| Nov 27, 2017 at 20:08 | comment | added | Omar Antolín-Camarena | @GregFriedman This is that argument, just phrased differently. (In particular $\Omega \Sigma \mathbb{R}P^2 \times \mathbb{R}P^2$ being connected is equivalent to $\pi_0(\mathbb{R}P^2)$ and $\pi_1(S(RP^2))$ being trivial.) | |
| Aug 27, 2012 at 21:11 | comment | added | Greg Friedman | This seems like overkill to me. Why not just use the long exact sequence of the pair and that $\pi_0(RP^2)$ and $pi_1(S(RP^2))$ are trivial? | |
