Heegaard and regular genus of 3-manifolds with boundary. P. Cristofori, C. Gagliardi, L. Grasselli (1995) Revista Matemática de la Universidad Complutense de Madrid By means of branched coverings techniques, we prove that the Heegaard genus and the regular genus of an orientable 3-manifold with boundary coincide.
