Discrete Applied Mathematics, 2021 Abstract Given a 3-uniform hypergraph H consisting of a set V of vertices, and T ⊆ V 3 triples, a null labelling is an assignment of ± 1 to the triples such that each vertex is contained in an equal number of triples labelled + 1 and − 1 . Thus, the signed degree of each vertex is zero.

The null divergence factor [PDF]
Publicacions Matemàtiques, 1997 Let (P,Q) be a C1 vectorfield defined in a open subset U ⊂ R2. We call a null divergence factor a C1 solution V (x, y) of the equation P ∂V ∂x + Q∂V ∂y = ∂P ∂x + ∂Q ∂y V . In previous works it has been shown that this function plays a fundamental role in the problem of the center and in the determination of the limit cycles.
