We characterize those closed -manifolds admitting smooth maps into -manifolds with only finitely many critical points, for . We compute then the minimal number of critical points of such smooth maps for and, under some fundamental group restrictions, also for . The main ingredients are King’s local classification of isolated singularities, decomposition theory, low dimensional cobordisms of spherical fibrations and 3-manifolds topology.
