Expected absolute random determinants and zonoids. (English) Zbl 0739.15015

This paper is about random matrices. It studies expectations of absolute values of determinants of random matrices which have as columns i.i.d. copies of a random vector. The results relates these to the volume of zonoids which are limits of zonotopes in the Hausdorff metric (a zonotope is a finite sum of line segments). Also some bounds are given.
