A Kunneth formula in monopole Floer homology

We establish a Kunneth formula in monopole Floer homology, which describes how the groups associated to 3-manifolds behave under the operation of connected sum. The proof is based on a rigidity principal for Floer theories satisfying the surgery exact triangle. This is joint work with Tom Mrowka and Peter Ozsvath.
