| Research Abstract |
Geometry of statistical manifolds are deeply related to various research fields, for example, information geometry, affine differential geometry, and Hessian geometry. In this project, we researched the submanifold theoretical aspects of statistical manifolds, in particular, we studied construction and classification problems for Hessian manifolds of constant Hessian sectional curvature, and for statistical hypersurfaces between such spaces. Furthermore, through the study of Riemannian submanifolds in complex space forms, we prepared to build complex geometry for statistical manifolds.
