On the gap metric and coprime factor perturbations
On the gap metric and coprime factor perturbations
New conditions are derived for when the distance between two linear systems in the gap metric is less than one. By including a coprimeness assumption in the coprime factor uncertainty description it is shown that an open ball in the gap metric is equivalent to an open ball phrased in terms of coprime factor perturbations. A new criterion is given for robust stabilization.

Abstract
New conditions are derived for when the distance between two linear systems in the gap metric is less than one. By including a coprimeness assumption in the coprime factor uncertainty description it is shown that an open ball in the gap metric is equivalent to an open ball phrased in terms of coprime factor perturbations. A new criterion is given for robust stabilization.
