Prerequisites:	Some degree of familiarity with differentiable manifolds and differential geometry of curves and surfaces. See below for required background knowledge.



Assumed background. To read on your own before the first day of class: Chapter 1 of [GHL] and Chapters 1 to 4 of Do Carmo's Differential Geometry of Curves and Surfaces.



Books: The book by Gallot, Hulin & LaFontaine ([GHL] from now on) is a good resource. I will also use parts of Sakai's book ([S] from now on), and Petersen's book ([P] from now on). The book by Berger "A panoramic view of Riemannian Geometry" ([B]) is a very good read. The following paper by Petersen is a very good summary of some global results in RG: "Aspects of global Riemannian Geometry" ([AGRG]).
