备   注：Abstract: De Giorgi-Moser iterations are important techniques in studying elliptic differential equations of divergence form. In this series of lectures, we study in details these iterations and their applications. De Giorgi iteration yields the Holder continuity of solutions, while Moser iteration yields Hanack inequality and the Holder continuity of solutions follows as a consequence. An important application is to get the Holder norm estimate of first derivatives of solutions of quasilinear elliptic equations.
