A calculus for branched spine of 3-manifolds
Francesco Costantino
We establish a calculus for branched spines of 3-manifolds by means of branched Matveev-Piergallini moves and branched bubble-moves. We briefly indicate some of its possible applic…

Triangulations of 3-manifolds, hyperbolic relative handlebodies, and Dehn filling
Francois Costantino, Roberto Frigerio, Bruno Martelli +1
We establish a bijective correspondence between the set T(n) of 3-dimensional triangulations with n tetrahedra and a certain class H(n) of relative handlebodies (i.e. handlebodies…
