Abstract: We relate $q$-strict convexity of compact convex sets $K\subset\R^d$ whose boundary $\partial K$ is a differentiable manifold of class $C^q$ to intrinsic curvature properties of $\partial K$. Furthermore we prove that the set of $q$-strictly convex sets is $F_\sigma$ of first Baire category.

Keywords: $q$-strict convexity, curvature

Classification (MSC2000): 52A20, 53A05
