Integrality of the Witten-Reshetikhin-Turaev 3-manifold invariant

We give a new definition of the WRT invariant of integral homology 3-spheres using the Hopf link pairing and the twist element. This leads to a unified invariant (defined for all roots of unity) and integrality of the WRT invariant. The new definition might lead to a way to categorify the WRT invariant. This is joint work with K. Habiro.
