О вложении инвариантных многообразий простейших потоков Морса-Смейла с гетероклиническими пересечениями
We study a structure of four-dimensional phase space decomposition on trajectories of Morse-Smale flows admitting heteroclinical intersections. We consider a class $G(S^4)$ of Morse-Smale flows on the sphere $S^4$ such that for any flow $f\in G(S^4)$ its non-wandering set consists of exactly four equilibria: source, sink and two saddles. Wandering set of such flows contains finite number of heteroclinical curves generating the intersection of invariant manifolds of saddle equilibria. We describe a topology of embedding of invariant manifolds of saddle equilibria that is the first step in a solution of topological classification problem.
