Symplectic mapping class group and the "Lagrangian sphere complex"

I only just noticed this question, so maybe it's too late, but here's an answer. Note that some symplectic manifolds (like $\mathbf{CP}^2$) contain no Lagrangian spheres, so this complex is then empt …

Lagrangian intersection Floer homology: understanding some assumptions

When you try and prove that $d^2=0$ ($d$ being the Floer differential) you need to look at the boundary of the moduli space of index 2 J-holomorphic strips with one boundary on $L_0$, one on $L_1$. Ce …

Lagrangian fibration on Schoen's Calabi-Yau 3-fold

I realise this is an old question (and by now you may already know the answer) but here's a way I think you can construct this fibration. Suppose that $E\stackrel{f}{\to}\mathbf{P}^1$ and $E'\stackre …
