Abstract
Approximation of convex bodies by either smooth convex bodies or polytopes has been considered frequently in convexity. There are two incentives for it. On the one hand approximation is used as a tool for investigations ranging from classical results on mixed volumes to questions concerning the ε-entropy of spaces of convex bodies, on the other hand there is an intrinsic geometric interest in the approximation problem itself.
