http://www.math.ias.edu/sp/gpdeThe goal of this course to provide an introduction to Monge-Ampere-type equations in conformal geometry and their applications. The plan of the course is the following: After providing some background material in conformal geometry, I will describe the k-Yamabe problem, a fully nonlinear version of the Yamabe problem, and discuss the associated ellipticity condition and its geometric consequences. Next, I will discuss a prori estimates, some basics of blow-up analysis, and entire solutions. In order to reduce some of the technical issues involved, while providing an important example the geometric applications of these equations, I will then narrow my focus to the case of four dimensions, and sketch a proof of existence in this case. Finally, I will point out some geometric applications of the equations in four dimensions.
