Higher moments of intrinsic volumes of random beta-prime polytopes

We consider beta-prime polytopes, i.e., the convex hulls of iid random points chosen according to beta-prime distributions in ${\mathbb{R}}^d$. After suitable scaling, beta-prime polytopes converge in distribution to the convex hulls of Poisson point processes with power-law intensity functions. We prove moment convergence for the volume and all intrinsic volumes. Beta-prime polytopes are the push-forwards of spherical random polytopes on the upper open half-sphere of the unit sphere $S^d\subset {\mathbb{R}}^{d+1}$. We prove convergence of moments of the spherical volume difference of the half-sphere and the spherical random polytopes.
