Abstract
We prove that in a real Hilbert space some extremal problems are Lipschitz stable with respect to the set in some special metric (Plis metric). We also consider the Lipschitz stability of such problems in the Hausdorff metric and characterize metrics on the space of closed bounded convex sets with uniformly continuous metric projection as function of the set.
