证明了对每个质心在原点的凸体K和\big(0,{1\over 2}\big)$中的每个\vareps\,存在一个凸多面体P,其顶点至多为e^{O(d)}\vareps ^{-{d-1\over 2}}$,使得$(1-\vareps)K\subset P\subset K$.
abstract:We prove that for every convex body $K$ with the center of mass at the origin and every $\varepsilon\in\big(0,{1\over 2}\big)$, there exists a convex polytope $P$ with at most $e^{O(d)}\varepsilon^{-{d-1\over 2}}$ vertices such that $(1-\varepsilon)K\subset P\subset K$.
