Abstract
For a given closed subset S of , we provide an inner approximation of S by sets satisfying the interior sphere condition. The fact that our approximation sets satisfy the interior sphere condition with variable radius, allows us to approach any corner and to use the Pompeiu-Hausdorff convergence even if the set S is unbounded.
