Ranks of collinear Morse forms
The rank of a closed 1-form is the rank of its group of periods. In the paper under review the author deals with foliations on closed manifolds induced by closed 1-forms with Morse type singularities. The author describes the set of the ranks of such forms and shows how it is related to the structure of the foliation and the manifold.
