The techniques in these lectures laid the groundwork for modern breakthrough mathematics. Use this text as a stepping stone to study:

Compares triangles in Riemannian spaces to triangles in space forms. 2. Minimal Surfaces

This is perhaps the most famous contribution of Schoen and Yau.

How positive or negative curvature affects the topological structure of a manifold (e.g., Gauss-Bonnet theorem applications).

If you are studying (not just geometry), these lectures are required cultural literacy.

The Yamabe problem—one of the most celebrated achievements of twentieth-century geometry—takes center stage in this chapter.

Deep explorations of how local curvature bounds (such as Ricci or sectional curvature) dictate the global topology and volume growth of a manifold.

Controls the volume growth of geodesic balls. 2. Minimal Surfaces and the Positive Mass Conjecture
