Abstract
For a convex body K in ℝn, the volume quotient is the ratio of the smallest volume of the circumscribed ellipsoids to the largest volume of the inscribed ellipsoids, raised to power 1/n. It attains its maximum if and only if K is a simplex. We improve this result by estimating the Banach-Mazur distance of K from a simplex if the volume quotient of K is close to the maximum.
