## Quantitative estimates of singular set and hessian estimate of harmonic functions on Einstein manifolds, Part 1

##### Abstract:

In these two talks, we will first discuss Cheeger and Naber's quantitative estimates of singular sets on manifolds with lower Ricci curvature and also review some recent developments. As consequences, we will discuss the hessian estimates of harmonic functions on Einstein manifolds.
