A question on surfaces in $\mathbb{P}^4$
In the first statement, you want the last $d_0$ to be a $d$?

$(M,\omega)$ not symplectomorphic to $(M,-\omega)$
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...
