| Apr 1 at 18:19 | comment | added | bonif | @MoisheKohan Thanks. And can they be complexified to $\mathbb{C^4}$? | |
| Apr 1 at 18:03 | comment | added | Moishe Kohan | @bonif: No, but there is an immersion in $C^2$. | |
| Apr 1 at 17:28 | comment | added | bonif | @MoisheKohan But not large exotic $\mathbb{R}^4$, that can't be embedded in $\mathbb{R}^4$ ? | |
| Dec 30, 2020 at 18:45 | comment | added | Moishe Kohan | What's more: Each small exotic $R^4$ is an open subset of ${\mathbb C}^2$, hence, has the induced complex structure from this embedding. | |
