Abstract:

In this paper we prove that if $(X,d,\mu)$ is a metric doubling space with segment property, then $\inf r(E)/r(B)>0$ if and only if $\inf \mu(E)/\mu(B)>0$, where the infimum is taken over any collection $\mathcal{C}$of balls $E, B$ such that $E\subset B\subset X$. As a consequence we show that if $X$ is a linear metric doubling space, then it must be finite dimensional.
