Multiframings of 3-manifolds

We investigate multiframings of a closed oriented 3-manifold. We show that multiframings give a geometric realization of the tensor product of the homotopy set of framings and. We prove that the Hirzebruch defect defines a bijection from the homotopy set of multiframings to for any connected closed oriented 3-manifold, and we prove that any multiframing defined near the boundary of a compact oriented 3-manifold extends to the bounded manifold.
