90C34 Semi-infinite programming

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
