  7. Abstract:
  8. We introduce a refinement of the Ozsváth-Szabó complex associated by Juhász [8] to a balanced sutured manifold (X; ). An algebra A is associated to the boundary of a sutured manifold. For a fixed class s of a Spinc structure over the manifold X, which is obtained from X by filling out the sutures, the Ozsváth-Szabó chain complex CF(X; ; s) is then defined as a chain complex with coefficients in A and filtered by the relative Spinc classes in Spinc(X; ). The filtered chain homotopy type of this chain complex is an invariant of (X; ) and the Spinc class s 2 Spinc(X). The construction generalizes the construction of Juhász. It plays the role of CF (X; s) when X is a closed three-manifold, and the role of CFK (Y;K; s) =⊕s2sCFK (Y;K; s); when the sutured manifold is obtained from a knot K inside a threemanifold Y . Our invariants thus generalize both the knot invariants of Ozsváth-Szabó and Rasmussen and the link invariants of Ozsváth and Szabó. We study some of the basic properties of the Ozsváth-Szabó complex corresponding to a balanced sutured manifold, including the behaviour under boundary connected sum, some form of stabilization for the complex, and an exact triangle generalizing the surgery exact triangles for knot Floer complexes
