Classification of Morse-Smale vector fields on 2-manifolds. (Ukrainian. English summary) Zbl 1091.57015

Summary: We consider the minimal Morse-Smale fields on a closed oriented 2-manifold. By means of chord diagrams we give necessary and sufficient conditions for topological equivalence of these fields. We also calculate the number of topologically non-equivalent fields on a pretzel.
