Foliation | Morse singularity | Reeb Stability
We study codimension one smooth foliations with Morse singularities. A characterization of the three-sphere in terms of the number of centers and saddles is obtained and generalizations of the classical theorems of Reeb, Haefliger and Novikov are given.
