You might ask: Why not just use do Carmo, Petersen, or Jost?

This chapter, originally published in the Annals of Mathematics Studies , is a treasure trove of open problems, organized into thematic sections: (I) Curvature and Topology, (II) Curvature and Complex Structure, (III) Submanifolds, (IV) The Spectrum, (V) Geodesics, (VI) Minimal Submanifolds, and (VII) General Relativity and Yang–Mills Equations. As one reviewer notes, this is a breathtaking collection—38 pages containing over 120 problem sections from 1982, and another 46-page list from 1991.

The volume's authority derives not merely from its content but from the two extraordinary mathematicians who authored it.

These lecture notes (often associated with the CBMS-NSF Regional Conference Series or compiled from their courses at institutions like UC San Diego and Princeton) are not a standard undergraduate textbook. They assume a strong background in:

As the Zentralblatt review notes, this chapter presents a simple proof of a key result by Anderson and Sullivan: the existence of bounded harmonic functions on complete manifolds whose sectional curvature is pinched between two negative constants.

This article provides a comprehensive overview of this legendary lecture series, its content, its philosophical approach, and guidance on how to legitimately access and utilize the material.

If you are a serious student, do not settle for shady links. Here is the ethical and effective roadmap:

The enduring demand for this text, often driven by digital searches for reference PDFs, stems from its unique pedagogical style. Rather than just presenting finished theorems, Schoen and Yau provide readers with the intuition behind the estimates.
