Bounds of the affine breadth eccentricity of convex bodies via semi-infinite optimization

Abstract: In this contribution we give a semi-infinite optimization approach to investigate the affine breadth eccentricity of convex bodies. An optimization-technique-based description of the minimal ellipsoid (Loewner-ellipsoid) of a convex body is used to derive an upper bound of the affine eccentricity in a very natural way. An additional special (integer programming) optimization problem shows that the obtained upper bound is the best possible one.

Keywords: Affine breadth eccentricity, minimal ellipsoid

Classification (MSC2000): 52A20, 52A40, 90C34
