Ghazouani's Morse–Smale conjecture for dilation surfaces

Let SS be a dilation surface that is not a translation surface, and let θS1\theta\in S^1 be a direction. A directional foliation is Morse-Smale if it has finitely many closed leaves and the c9c9- and b1b1-limit set of every regular leaf is a closed leaf. Ghazouani's conjecture. For a full-measure set of directions in S1S^1, the directional foliation on SS is Morse-Smale.

This conjecture predicts that Morse-Smale behaviour is generic among directional foliations on dilation surfaces that are not translation surfaces. The source notes that it is known for the Disco surface, while no counterexample is known in general.
