Classifying expanding attractors on figure eight knot complement space and non-transitive Anosov flows on Franks-Williams manifold

The path closure of figure eight knot complement space, $N_0$, supports a natural DA (derived from Anosov) expanding attractor. Using this attractor, Franks-Williams constructed the first example of non-transitive Anosov flow on the manifold $M_0$ obtained by gluing two copies of $N_0$ through identity map along their boundaries, named by Franks-Williams manifold. In this paper, our main goal is to classify expanding attractors on $N_0$ and non-transitive Anosov flows on $M_0$. We prove that, up to orbit-equivalence, the DA expanding attractor is the unique expanding attractor supported by $N_0$, and the non-transitive Anosov flow constructed by Franks and Williams is the unique non-transitive Anosov flow admitted by $M_0$. Moreover, more general cases are also discussed. In particular, we completely classify non-transitive Anosov flows on a family of infinitely many toroidal $3$-manifolds with two hyperbolic pieces, obtained by gluing two copies of $N_0$ through any gluing homeomorphism.
