     Furthermore, ${\displaystyle \phi (M)}$ is starshaped with respect to ${\displaystyle p_{0}}$, Hausdorff close and almost-isometric to the geodesic sphere ${\displaystyle S(p_{0},R_{0})}$, where ${\displaystyle R_{0}=\arcsin {\frac {1}{\sqrt {1+\|H\|_{\infty }^{2}}}}}$.

2. (mathematics) of a subset S of a vector space, containing a point ${\displaystyle x_{0}}$ such that the connecting line from ${\displaystyle x}$ to ${\displaystyle x_{0}}$ is entirely in ${\displaystyle S}$, for every ${\displaystyle x\in S}$

   Hyponym: convex
