Curvature and $q$-strict convexityLeoni Dalla and Evangelia SamiouDepartment of Mathematics, University of Athens Panepistimioupolis, GR-15784 Athens, Greece, e-mail: ldalla@math.uoa.gr; University of Cyprus, Department of Mathematics and Statistics, P.O. Box 20537, 1678 Nicosia, Cyprus, e-mail: samiou@ucy.ac.cyAbstract: We relate $q$-strict convexity of compact convex sets $K\subset\R^d$ whose boundary $ tial K$ is a differentiable manifold of class $C^q$ to intrinsic curvature properties of $ tial 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 Full text of the article (for subscribers):
