摘要
Let x(1),...,x(N) be independent random points distributed according to an isotropic log-concave measure mu on R-n, and consider the random polytope K-N := conv{+/- x(1),...,x(N)}. We provide sharp estimates for the quermassintegrals and other geometric parameters of K-N in the range cn <= N <= exp(n); these complement previous results from [13] and [14] that were given for the range cn <= N <= exp(root n). One of the basic new ingredients in our work is a recent result of E. Milman that determines the mean width of the centroid body Z(q)(mu) of mu for all 1 <= q <= n.
