| Mar 12, 2018 at 16:20 | comment | added | Emily Maw | The answer to the question linked by @AliTaghavi gives an example when $M$ is a manifold with boundary. Namely a symplectic filling of a hyperbolic 3-manifold, $Y$, such that $b_1(Y)>0$ and all orientation-preserving self-homeomorphisms of Y induce the trivial map on $H^2(Y)$. That post doesn't have an answer for closed $M$ though... | |

| Aug 29, 2017 at 18:29 | comment | added | Will Sawin | @AliTaghavi Isn't there an answer to your question, which therefore is also an answer to this question, at the linked post? So it's a little more than just related... | |

| Aug 24, 2017 at 11:58 | comment | added | Ali Taghavi | In your second line of your question, I guess that you mean "In particular a chiral manifold of dimension $4n+2$ with a symplectic structure, would be a desired example. Yes? | |
