Query: Knot Floer homology of fibred knots and Floer homology of surface
  diffeomorphisms   We prove that the Knot Floer homology group of a fibred knot of genus g in
the Alexander grading 1-g is isomorphic to a version of the fixed point Floer
homology of an area-preserving representative of the monodromy.
