The other half of the theorem of Kupka and Smale says for a residual subset of all vectorfields, the stable and unstable manifolds of closed orbits meet transversally. Theorem 3 proves this property is true for a residual subset of all volume preserving diffeomorphisms, volume preserving vectorfields, and symplectic diffeomorphisms.

Webthe Kupka-Smale property for smooth vector elds and maps is prevalent, that is, typical in the metric sense. In addition to the aforementioned work, the Kupka-Smale theorem has been proven in many settings, including smooth endomorphisms of a com-pact manifold [Shu69], real-analytic di eomorphisms [BT86, Les83] and Webhave full measure. In particular, the Kupka-Smale diffeomorphisms (those having only hyperbolic periodic points whose stable and unstable manifolds meet trans- versely) have full measure. In fact, by a theorem of S0tomayor [6], [15], for a residual set a arcs ~, ~t fails to be Kupka-Smale for at most countably many t's in [0,i].
