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. |

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

@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. |

If a (linear) relation maps Lagrangian subspaces to Lagrangian subspaces, is it a Lagrangian relation?
Good point, Max. |

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

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. |
