Ozsváth and Szabó used the knot filtration on CF̂(S3) to define the τ–invariant for knots in the 3–sphere. We generalize their construction and define a collection of τ–invariants associated to a knot K in a rational homology sphere Y . We then show that some of these invariants provide lower bounds for the genus of a surface with boundary K properly embedded in a negative-definite 4–manifold with boundary Y .
Keywords: Heegaard Floer, knot invariants, genus bound, rational homology spheres
