An application of the Morse theory to foliated manifolds
Kazuhiko Fukui · Nagoya Mathematical Journal · 1974
In [5], R. Thorn has started the study of the foliated structures by using the Morse theory. Recently K. Yamato [7] has studied the topological properties of leaves of a codimension one foliated manifold by investigating the “critical points” of variation equation of the given one-form.
