Geodesics and Distance, possible to define metric distance functions. We shall study when these distance functions are smooth and show the existence of the smooth distance functions introduced in chapter 3 We also classify complete simply connected manifolds of constant curvature; showing that they are the ones we have already constructed in chapters 1 and 4

Examples,, and the Riemannian version of the Schwarzschild metric. We also offer a local characterization of certain warped products and rotationally symmetric constant curvature metrics in terms of the Hessian of certain modified distance functions.

Symmetric Spaces and Holonomy,e is a brief introduction to holonomy and the de Rham decomposition theorem. We give a few interesting consequences of this theorem and then proceed to discuss how holonomy and symmetric spaces are related. Finally, we classify all compact manifolds with nonnegative curvature operator.

er, its application in guanidine synthesis has also been proved. Examples of the preparation of guanidines using cyanamides that react with derivatised amines as well as the use of copper-catalysed cross-coupling chemistry are also presented. Moreover, cyclic guanidines such as 2-aminoimidazolines (
