For a transversal pair of closed Lagrangian submanifolds $L, L'$ of a symplectic manifold $M$ so that $\pi_{1}(L)=\pi_{1}(L')=0=c_{1}|_{\pi_{2}(M)}=\omega|_{\pi_{2}(M)}$ and a generic almost complex structure $J$ we construct ...

When $L$ and $L'$ are hamiltonian isotopic, these pages coincide (up to a horizontal translation) with the terms of the Serre-spectral sequence of the path-loop fibration $\Omega L\to PL\to L$. Among other applications we prove that, in this case, each point $x\in L\backslash L'$ belongs to some pseudo-holomorpic strip of symplectic area less than the Hofer distance between $L$ and $L'$.Lire moins >
