Round fold maps of n--dimensional manifolds into $R^{n - 1}$

Naoki Kitazawa, Osamu Saeki

We determine those smooth $n$ --dimensional closed manifolds with $n \geq 4$ which admit round fold maps into $R^{n - 1}$ , i.e.\ fold maps whose critical value sets consist…

Round fold maps on $3$ --manifolds

Naoki Kitazawa, Osamu Saeki

We show that a closed orientable 3--dimensional manifold admits a round fold map into the plane, i.e. a fold map whose critical value set consists of disjoint simple closed curves…
