Asymptotics of the convex hull of spherical samples

Enkelejd Hashorva

摘要:

本文考虑了$R^d$中球对称样本的凸包。我们的主要贡献是一些新的渐近结果的期望的顶点数,面数,面积和体积的凸包假设的边缘分布是在Gumbel最大-吸引区域。此外,我们简要地讨论了其他两个模型,假设边缘分布是定期变化或$O$ -定期变化。

英文摘要:

In this paper we consider the convex hull of a spherically symmetric sample in $R^d$. Our main contributions are some new asymptotic results for the expectation of the number of vertices, number of facets, area and the volume of the convex hull assuming that the marginal distributions are in the Gumbel max-domain of attraction. Further, we briefly discuss two other models assuming that the marginal distributions are regularly varying or $O$-regularly varying.
