Abstract

Given a taut depth-one foliation F\mathcal{F} in a closed atoroidal 3-manifold MM transverse to a pseudo-Anosov flow ϕ\phi without perfect fits, we show that the universal circle coming from leftmost sections Sleft\mathfrak{S}_\mathrm{left} associated to F\mathcal{F}, constructed by Thurston and Calegari-Dunfield, is isomorphic to the ideal boundary of the flow space associated to ϕ\phi with natural structure maps. As a corollary, we use a theorem of Barthelm\'e-Frankel-Mann to show that there is at most one pseudo-Anosov flow without perfect fits transverse to F\mathcal{F} up to orbit equivalence.
