Ekaterina Pervova Carlo Petronio April 21, Abstract We introduce a complexity c(X) ∈ Nfor pairs X= (M,L), where M is a closed orientable 3-manifold and L⊂ M is a link. The deﬁnition employs simple spines, but for well-behaved X’s we show that c(X) equals the minimal number of tetrahedra in a triangulation of M con-taining Lin its
