Outline of Final Research Achievements

In this research, we have formulated mathematical framework of inverse problems about persistent homology, and have developed a software which is applicable to real data. First, in direct problems, we studied the correspondence from point cloud data to persistence diagrams as differentiable maps. Then, we developed an algorithm to solve inverse solutions by using Newton method based on implicit function theorem. The developed software was applied to practical structural analysis of proteins and materials science.
