  1. How to take shortcuts in Euclidean space: making a given set into a short quasi-convex set.

    Authors: Raanan Schul, Jonas Azzam

    Abstract

    For a given connected set $\Gamma$ in $d-$dimensional Euclidean space, we
    construct a connected set $\tilde\Gamma\supset \Gamma$ such that the two sets
    have comparable Hausdorff length, and the set $\tilde\Gamma$ has the property
    that it is quasiconvex, i.e. any two points $x$ and $y$ in $\tilde\Gamma$ can
    be connected via a path, all of which is in $\tilde\Gamma$, which has length
    bounded by a fixed constant multiple of the Euclidean distance between $x$ and
    $y$.

    Abstract

    For $d\geq 2$, we construct a doubling measure $\nu$ on $\R^d$ and a
    rectifiable curve $\Gamma$ such that $\nu(\Gamma)>0$.
