This paper proves a map from flow-spines to contact structures is surjective.
A flow-spine of a 3-manifold is a spine admitting a flow that is transverse to the spine, where the flow in the complement of the spine is diffeomorphic to a constant flow in an open ball. We say that a contact structure on a closed, connected, oriented 3-manifold is supported by a flow-spine if it has a contact form w…

The abstract extends Reidemeister theorem to 3-manifolds using diagrams of links and bands.
