报告摘要：The figure-eight knot exterior N supports a natural DA (derived from Anosov) expanding attractor, with which Franks-Williams constructed the first example of non-transitive Anosov flow. This flow lies in a 3-manifold M which is the double of N. We call M the Franks-Williams manifold. We prove that, up to orbit-equivalence, this DA expanding attractor is the unique expanding attractor supported by N. We also show that, up to orbit-equivalence, the non-transitive Anosov flow constructed by Franks and Williams is the unique non-transitive Anosov flow supported by M. This is a joint work with Yang Jiagang.
