| Nov 6, 2013 at 19:57 | comment | added | Douglas Zare | By the way, the minimal ellipsoid containing $K$ is more usually called Löwner's ellipsoid. John's ellipsoid is the maximal volume ellipsoid contained in $K$. | |
| Nov 6, 2013 at 16:13 | comment | added | Bill Johnson | Let's see. Specialize to the case where $K'$ is itself an ellipsoid. If what you want to be true were indeed true, you would get that the John's ellipsoid for $K$ must be contained in $K'$. In other words, the John's ellipsoid for $K$ would be contained in the intersection of all ellipsoids containing $K$. | |
