The θ-exterior sphere condition, φ-convexity, and local semiconcavity
We consider sets S⊂Rn satisfying a locally uniform exterior sphere condition called the θ-exterior sphere condition . It is shown that under wedgedness of S, this coincides with the φ-convexity property studied by Colombo and Marigonda (2005) [5]. This generalizes and improves upon the main result o...
