Research Abstract

It is one of the main problems to investigate relations between analytic invariants of surfaces or its higher dimensional analogue manifolds and geometric structures, curvatures and topology, which is called the spectral geometry. On the other hands, there are many researches as inverse problems, which is the mathematics related to CT-scanner and non destructive investigation. Here, we consider the spectral inverse problem on manifolds with boundary, which lies the intersection of the above fields. Especially, relating to the stability that is how much know about the geometric structure when one only knows incomplete analytic data with errors, we consider relations of the boundary distance with the inner metric and topology.
