Аннотация:
In this paper we consider nonsingular Morse – Smale flows on closed orientable 3-manifolds, under the assumption that among the periodic orbits of the flow there is only one
saddle orbit and it is twisted. It is found that any manifold admitting such flows is either a lens
space, or a connected sum of a lens space with a projective space, or Seifert manifolds with base
sphere and three special layers. A complete topological classification of the described flows is
obtained and the number of their equivalence classes on each admissible manifold is calculated.
