Abstract: We address the issue of measuring the degree of axial symmetry of a convex cone. By following an axiomatic approach, we introduce and explore the concept of axial symmetry index. This concept is illustrated with the help of several interesting examples. By way of application, we establish a conic version of the Blekherman inequality concerning the quality of the approximation of a convex body by its inscribed ellipsoid.

Keywords: Convex cone, axially symmetric cone, axial symmetry index, generalized reflection matrix.

Category 1: Linear, Cone and Semidefinite Programming

Citation: To appear in Journal of Convex Analysis, Vol. 26, 2019.
