Abstract

The set of all absolute normalized norms on $\mathbb{R}^{2}$ (denoted by $AN_{2}$ ) has a convex structure with respect to the usual operation. In a previous article, N. Komuro, K.-S. Saito, and K.-I. Mitani calculated the James constants of $(\mathbb{R}^{2},\Vert \cdot\Vert )$ when $\Vert \cdot\Vert$ is an extreme point of $AN_{2}$ . In this article, we calculate the James constant of its dual space.
