Uniqueness conjecture for almost transverse pseudo-Anosov flows

Let F\mathcal{F} be a taut foliation of an atoroidal 3-manifold MM which is not R\mathbb{R}-covered. A foliation is almost transverse to a flow when it satisfies the almost-transversality condition used in the paper, and a pseudo-Anosov flow has no perfect fits when its stable and unstable foliations have no perfect-fit configurations. Uniqueness conjecture. If F\mathcal{F} is almost transverse to a pseudo-Anosov flow φ\varphi with no perfect fits, then φ\varphi is the unique pseudo-Anosov flow almost transverse to F\mathcal{F}. This generalizes the established uniqueness result for depth one foliations; the conjecture concerns the uniqueness problem beyond the R\mathbb{R}-covered and depth one cases.
