Volume Convergence of Gromov-Hausdorff topology (I)

Chao-Ming Lin (National Taiwan University)

Abstract

In this talk, we consider a sequence of compact *n*-dimensional Riemannian manifolds with marked point which converge to a smooth *n*-dimensional Riemannian manifold with marked point in the pointed Gromov-Hausdorff topology. The goal here is to establish a volume convergence under some Ricci curvature bound. In fact, we can remove the restriction on the smoothness and get a volume convergence of Hausdorff measure.

In the first talk, I will assume some estimate, and prove the volume convergence. In the second talk, I will show the detail estimates.
