Riemann， undoubtedly the greatest mathematician of the 19th century，aimed at introducing the notion of a manifold and its structures. The prob-lem involved great difficulties. But， with hypotheses on the smoothness ofthe functions in question， the issues can be settled satisfactorily and thereis now a complete treatment. Traditionally， the structure being focused on is the Riemannian metric，which is a quadratic differential form. Put another way， it is a smoothlyvarying family of inner products， one on each tangent space. The resultinggeometry —— Riemannian geometry —— has undergone tremendous develop-ment in this century. Areas in which it has had significant impact includeEinsteins theory of general relativity， and global differential geometry. In the context of Riemanns lecture， this restriction to a quadratic dif-ferential form
