Abstract

The concept of the canonical divergence is defined for dually flat statistical manifolds in terms of the Legendre transform between dual affine coordinates. In this article, we introduce a new two point function defined for any triple $(g, \nabla, \nabla^{*})$ of a Riemannian metric $g$ and two affine connections $\nabla$ and $\nabla^{*}$. We show that this interprets the canonical divergence without refering to the existence of special coordinates (dual affine coordinates) but in terms of only classical mechanics concerning $\nabla$- and $\nabla^{*}$-geodesics. We also discuss the properties of the two point function and show that this shares some important properties with the canonical divergence defined on dually flat statistical manifolds.
