We prove the existence of a spectral sequence for Lagrangian Floer homology which converges to the Floer homology of the image of a Lagrangian submanifold under multiple fibred Dehn twists. The term of the sequence is given by the hypercube of "resolutions" of the Dehn twists involved. The proof relies on the exa…
