Mean curvature flow with surgery of mean convex surfaces in $\mathbb{R}^3$ (1309.1461v2)

Abstract: We define a notion of mean curvature flow with surgery for two-dimensional surfaces in $\mathbb{R}^3$ with positive mean curvature. Our construction relies on the earlier work of Huisken and Sinestrari in the higher dimensional case. One of the main ingredients in the proof is a new estimate for the inscribed radius established by the first author.
