    Jordan curves and funnel sections

    Get PDF
    We study the case when solution of an ODE at a given initial condition fail to be unique and investigate what are the possible time-1 sections of the `solution funnel'. Along the way we give construction of a natural complete metric on the space of Jordan curves and prove that the generic Jordan curve is nowhere pierceable by arcs of finite length.Comment: 22 pages, 16 figure

    H\"older foliations, revisited

    Full text link
    We investigate transverse H\"older regularity of some canonical leaf conjugacies in partially hyperbolic dynamical systems and transverse H\"older regularity of some invariant foliations. Our results validate claims made elsewhere in the literature.Comment: 52 pages, to appear in Journal of Modern Dynamic
