Outline of Final Research Achievements

We developed the convergence theory of metric measure spaces with Ricci curvature bonded from below. In particular we studied, BV-functions, Sobolev functions, heat kernel, Weyl's law, local spectral convergence, spectral convergence of CD spaces, embedding into L2 space via heat kernel, characterization of non-collapsed spaces, sphere theorem, and degeneration of K3 surfaces.

Academic Significance and Societal Importance of the Research Achievements

この世のいたるところに図形がある.幾何学はそれを調べることが役目である.図形の中でもたんすのように角がある図形も日常にはあふれている.幾何学では,角がある図形と角がない図形を区別することが多く,後者の図形のほうが研究しやすい.本研究は前者の図形を微分積分を使って研究した.角がある図形の上での微分積分学への貢献の一助を担った研究となったと思う.
