## The Demyanov metric and some other metrics in the family of convex sets.(English)Zbl 1364.52004

Summary: We describe some known metrics in the family of convex sets which are stronger than the Hausdorff metric and propose a new one. These stronger metrics preserve in some sense the facial structure of convex sets under small changes of sets.
