Abstract
New conditions are derived for when the distance between two linear sy stems in the gap metric is less than one. By including a coprimeness a ssumption in the coprime factor uncertainty description it is shown th at an open ball in the gap metric is equivalent to an open ball phrase d in terms of coprime factor perturbations. A new criterion is given f or robust stabilization.
