comment How to prove Arnold Conjecture without using S^1 localization?
Fyi, Katrin Wehrheim gave another summary at math.berkeley.edu/~katrin/teach/regularization/L15.pdf -- which may be easier to read, since it's in the context of a regularization class she taught in Spring 2014 at Berkeley.

comment Can a symplectic manifold be recovered from its Lagrangians?
@ThomasKragh Good point! Are you using Nadler--Zaslow for the quasiequivalence of Fukaya categories?

comment Can a symplectic manifold be recovered from its Lagrangians?
@Sasha That's true, though if you add the assumption that $X$ has ample canonical or anticanonical bundle and assume that the equivalence of derived categories is exact, then it's still true.

Thanks! Do you know anything about what happens when the "smoothness" hypothesis is dropped?

comment If a (linear) relation maps Lagrangian subspaces to Lagrangian subspaces, is it a Lagrangian relation?
I bet it's true under those hypotheses. Decompose $\Lambda$ as the direct sum of $A \oplus \{0\}$, $\text{graph}(\varphi)$, $\{0\} \oplus B$ for subspaces $A,B$ and $\varphi$ an isomorphism from a complement of $A$ to a complement of $B$. Then $A$ and $B$ must be isotropic. But I'm not sure how to show that $\text{graph}(\varphi)$ is isotropic.
