Homogeneous Structures on $S^{2} \times R$ and $H^{2} \times R$

Yu Ohno

We determine all the homogeneous structure tensors on $S^{2} \times R$ and $H^{2} \times R$ . This work together with previous articles yields a complete…

A characterization of the alpha-connections on the statistical manifold of multivariate normal distributions

Shimpei Kobayashi, Yu Ohno

We study a statistical manifold $(N, g^{F}, \nabla^{A}, \nabla^{A *})$ of multivariate normal distributions, where $g^{F}$ is the Fisher metric and $\nabla^{A}$ is the Amari-C…
