Abstract |
We make use of the action of H1(Y) in Heegaard Floer homology to generalize the Ozsvath-Szabo correction terms
for 3-manifolds with standard HF∞, introducing intermediate d-invariants.
We establish the basic properties of these invariants: conjugation invariance, behavior under orientation reversal,
additivity, and Spinc-rational homology cobordism invariance. |
