Research Abstract |
A pair (D,g) of a flat connection D and a Riemannian metric g is said to be a Hessian structure if g is locally expressed by Hessian with respect to D. The geometry of Hessian structures is deeply related to information geometry as well as Kahler geometry. In this project we intended to the fundamental study of Hessian structures and its application to information geometry. We published a book in Japanese titled "Hessian Geometry" including the results obtained in this project. We are now translating the book in English.
