Gaussian Curvature and the Gauss Map, remarkable property, established in Chapter 10, that it is unchanged when the surface is bent without stretching, a property that is not shared by the principal curvatures. In the present chapter, we discuss some more elementary properties of the gaussian and mean curvatures, and what a knowledge of them implies about the geometry of the surface.

Minimal Surfaces,rn out to be surfaces whose mean curvature vanishes everywhere. The study of these so-called minimal surfaces was initiated by Euler and Lagrange in the mid-18th century, but new examples of minimal surfaces have been discovered quite recently.

The real importance of the Gauss—Bonnet theorem is as a prototype of analogous results which apply in higher dimensional situations, and which relate . properties to . ones. The study of such relations is one of the most important themes of 20th century Mathematics.
