| Sep 30, 2020 at 20:28 | comment | added | Michael Albanese | @RobertBryant: I meant no example where $M\times M$ is Kähler. Note that the question has been edited since my comment (previously it asked whether there was an example with $M\times M$ complex). | |
| Sep 30, 2020 at 20:23 | comment | added | Robert Bryant | Obviously, there is no symplectic structure (and hence no Kähler structure) on any smooth manifold homeomorphic to $S^3\times S^3$ because $H^2(S^3\times S^3) = 0$. | |

| Sep 30, 2020 at 20:14 | comment | added | Michael Albanese | There is a complex structure on $S^3\times S^3$, see Calabi-Eckmann manifolds. I am not aware of any Kähler examples. | |
