A C⁰ estimate for nearly umbilical surfaces
@inproceedings{DeLellis2006ACE, title={A C⁰ estimate for nearly umbilical surfaces}, author={Camillo De Lellis and Stefan M{\"u}ller}, year={2006}, url={https://api.semanticscholar.org/CorpusID:125403037} }
Let Σ ⊂ R 3 be a smooth compact connected surface without boundary. Denote by A its second fundamental form and by A the tensor A−(tr A/2)Id. In [4] we proved that, if ‖A‖ L 2 (Σ) is small, then Σ is W 2,2-close to a round sphere. In this note we show that, in addition, the metric of Σ is C 0–close to the standard metric of S 2.
