Scattering by Obstacles, though a similar analysis can be given for obstacles in . whenever . is odd. The Huygens principle plays an important role in part of the analysis, and for that part the situation for . even is a little more complicated, though a theory exists there also.

Connections and Curvature,§1 on connections is somewhat parallel to the study of the natural connection on a Riemannian manifold made in §11 of Chap. 1, but here we also study the curvature of a connection. Material in §2 on second covariant derivatives is connected with material in Chap. 2 on the Laplace operator. Ideas dev

Connections and Curvature,es related to the proof of the uniformization theorem and for applications to the Riemann–Roch theorem in Chap. 10. Furthermore, it serves as a transition to more advanced material presented in §§6–8.

human collective behaviour, of the societies they created, and of the social and political structures that people had built. These too had long been the subjects of investigation by religious groups, individual philosophers, and so on, but they had not become the subjects of scientific investigation
