Regularity of minimal surfaces : a self-contained proof Mather, Kevin
In this thesis, a self-contained proof is given of the regularity of minimal surfaces via viscosity solutions, following the ideas of L.Caffarelli,X.Cabré , O.Savin, E.Giusti and J.Roquejoffre, where we expand upon the ideas and give full details on the approach. Basically the proof of the program consists of four parts: 1) Density and measure estimates, 2) Viscosity solution methods of elliptic equations , 3) a geometric Harnack inequality and 4) iteration of the De Giorgi ﬂatness result.
