摘要：

Let K be a symmetric convex body in R-N for which B-2(N) is the ellipsoid of minimal volume. We provide estimates for the geometric distance of a 'typical' rank n projection of K to B-2(n), for 1 less than or equal to n < N. Known examples show that the resulting estimates are optimal (up to numerical constants) even for the Banach-Mazur distance.
