| Aug 24, 2019 at 3:15 | comment | added | Ali Taghavi | @LSpice I guess fixed point free maps in odd dimension is constructed linearly with a combination of 90 degree rotation and complex conjugation. But for quaternioun all projective space have FPP (both odd and even). This is proved in Hatcher book. | |

| Aug 24, 2019 at 3:07 | comment | added | Ali Taghavi | @LSpice the only complex projective space with fixed point property are $\mathbb{C}P^{2k}$. Please read the revise history of this question. I had changed $\mathbb{C}P^2$ to CP^3, based on the same reason you mentioned. | |
| Aug 24, 2019 at 2:59 | comment | added | LSpice | Note that giving a map $f$ as in the question is equivalent to giving a self-map of $P^3\mathbb C$ without fixed points. (I don't know off the top of my head if such a thing exists, but I'll bet someone does.) | |
