Title: Curvature Invariants on Statistical Manifolds and thier Submanifolds

Speaker: Ion Mihai (University of Bucharest, Romania)

Abstract: Statistical manifolds were introduced by S. Amari [1]. In particular, Hessian manifolds are statistical manifolds of constant curvature 0. The geometry of statistical manifolds and their submanifolds is a modern topic of research in pure and applied mathematics. M.E. Aydin, A. Mihai and the present author [2] obtained geometric inequalities for the scalar curvature and Ricci curvature associated to the dual connections for submanifolds in statistical manifolds of constant curvature. In [3], the same authors proved a generalized Wintgen inequality for such submanifolds, with respect to a sectional curvature introduced by B. Opozda [6]. Recently, in co-operation with A. Mihai [5], we established a Euler inequality and a Chen-Ricci inequality for submanifolds in Hessian manifolds of constant Hessian curvature. Recently, we proved Chen first inequality on such submanifolds (see [4]). The present talk is a survey on basic notions and recent results in this topic.
