Branched Spines and Contact Structures on 3-manifolds
Riccardo Benedetti, Carlo Petronio
We introduce and analyze the characteristic foliation induced by a contact structure on a branched surface, in particular a branched standard spine of a 3-manifold. We extend to (f…

Torsion Invariants of Combed 3-Manifolds with Boundary Pattern and Legendrian Links
Riccardo Benedetti, Carlo Petronio
We extend Turaev's definition of torsion invariants of 3-dimensional manifolds equipped with non-singular vector fields, by allowing (suitable) tangency circles to the boundary, an…
