Mean curvature flow with surgery. (English) Zbl 1370.53046

The general aim of the interesting paper under review is to give a new proof for the existence of mean curvature flow with surgery for \(2\)-convex hypersurfaces in \(\mathbb{R}^N,\) working for all \(N\geq3.\) The authors’ main focus is on shortness, brevity and simplicity. Moreover, the proofs work for mean convex surfaces in \(\mathbb{R}^3,\) which was left as an open problem after [G. Huisken and C. Sinestrari, Invent. Math. 175, No. 1, 137–221 (2009; Zbl 1170.53042)]. Furthermore, anticipating future applications, the authors derive a priori estimates in a completely local and very flexible setting.
