Graphs of NMS flows on \(S^{3}\) with knotted saddle orbits and no heteroclinic trajectories. (English) Zbl 1137.37312

Summary: We consider NMS systems on \(S^{3}\) without heteroclinic trajectories connecting two saddles orbits and we build the dual graphs associated with this kind of flows. We prove that flows coming from essential attachments of orientable round 1-handles can be reproduced from the corresponding dual graph.
