From the preface:Many years have passed since the first edition. However, the encouragements of various readers and friends have persuaded us to write this third edition. During these years, Riemannian Geometry has undergone many dramatic developments. Here is not the place to relate them. The reader can consult for instance the recent book [Br5]. However, Riemannian Geometry is not only a fascinating field in itself. It has proved to be a precious tool in other parts of mathematics. In this respect, we can quote the major breakthroughs in four-dimensional topology which occurred in the eighties and the nineties of the last century see for instance [L2]. In another direction, Geometric Group Theory, a very active field nowadays cf. But let us stop hogging the limelight. This is just a textbook. We hope that our point of view of working intrinsically with manifolds as early as possible, and testing every new notion on a series of recurrent examples see the introduction to the first edition for a detailed description , can be useful both to beginners and to mathematicians from other fields, wanting to acquire some feeling for the subject. Riemannian geometry was first put forward in generality by Bernhard Riemann in the 19th century. It deals with a broad range of geometries whose metric properties vary from point to point, including the standard types of non-Euclidean geometry. Every smooth manifold admits a Riemannian metric , which often helps to solve problems of differential topology. It also serves as an entry level for the more complicated structure of pseudo-Riemannian manifolds , which in four dimensions are the main objects of the theory of general relativity. Other generalizations of Riemannian geometry include Finsler geometry. There exists a close analogy of differential geometry with the mathematical structure of defects in regular crystals. Dislocations and disclinations produce torsions and curvature. What follows is an incomplete list of the most classical theorems in Riemannian geometry. The choice is made depending on its importance and elegance of formulation. Most of the results can be found in the classic monograph by Jeff Cheeger and D. Ebin see below. The formulations given are far from being very exact or the most general. This list is oriented to those who already know the basic definitions and want to know what these definitions are about. In all of the following theorems we assume some local behavior of the space usually formulated using curvature assumption to derive some information about the global structure of the space, including either some information on the topological type of the manifold or on the behavior of points at "sufficiently large" distances.

During , Riemann went to Hanover to live with his grandmother and attend lyceum middle school years. In high school, Riemann studied the Bible intensively, but he was often distracted by mathematics. His teachers were amazed by his adept ability to perform complicated mathematical operations, in which he often outstripped his instructor's knowledge. In , at the age of 19, he started studying philology and Christian theology in order to become a pastor and help with his family's finances. However, once there, he began studying mathematics under Carl Friedrich Gauss specifically his lectures on the method of least squares. Gauss recommended that Riemann give up his theological work and enter the mathematical field; after getting his father's approval, Riemann transferred to the University of Berlin in Riemann held his first lectures in , which founded the field of Riemannian geometry and thereby set the stage for Albert Einstein 's general theory of relativity. Although this attempt failed, it did result in Riemann finally being granted a regular salary. He was also the first to suggest using dimensions higher than merely three or four in order to describe physical reality. Riemann was a dedicated Christian, the son of a Protestant minister, and saw his life as a mathematician as another way to serve God. During his life, he held closely to his Christian faith and considered it to be the most important aspect of his life. Riemann refused to publish incomplete work, and some deep insights may have been lost forever. Riemann's tombstone in Biganzolo Italy refers to Romans : [9]. Riemann's published works opened up research areas combining analysis with geometry. These would subsequently become major parts of the theories of Riemannian geometry , algebraic geometry , and complex manifold theory. This area of mathematics is part of the foundation of topology and is still being applied in novel ways to mathematical physics. In , Gauss asked Riemann, his student, to prepare a Habilitationsschrift on the foundations of geometry. It was only published twelve years later in by Dedekind, two years after his death. Its early reception appears to have been slow but it is now recognized as one of the most important works in geometry. The subject founded by this work is Riemannian geometry. Riemann found the correct way to extend into n dimensions the differential geometry of surfaces, which Gauss himself proved in his theorema egregium. The fundamental object is called the Riemann curvature tensor. For the surface case, this can be reduced to a number scalar , positive, negative, or zero; the non-zero and constant cases being models of the known non- Euclidean geometries. Riemann's idea was to introduce a collection of numbers at every point in space i. Riemann found that in four spatial dimensions, one needs a collection of ten numbers at each point to describe the properties of a manifold , no matter how distorted it is. This is the famous construction central to his geometry, known now as a Riemannian metric. In his dissertation, he established a geometric foundation for complex analysis through Riemann surfaces , through which multi-valued functions like the logarithm with infinitely many sheets or the square root with two sheets could become one-to-one functions. Complex functions are harmonic functions that is, they satisfy Laplace's equation and thus the Cauchy—Riemann equations on these surfaces and are described by the location of their singularities and the topology of the surfaces. His contributions to this area are numerous. The famous Riemann mapping theorem says that a simply connected domain in the complex plane is "biholomorphically equivalent" i. Here, too, rigorous proofs were first given after the development of richer mathematical tools in this case, topology. For the proof of the existence of functions on Riemann surfaces he used a minimality condition, which he called the Dirichlet principle. Karl Weierstrass found a gap in the proof: Riemann had not noticed that his working assumption that the minimum existed might not work; the function space might not be complete, and therefore the existence of a minimum was not guaranteed. Through the work of David Hilbert in the Calculus of Variations, the Dirichlet principle was finally established. Otherwise, Weierstrass was very impressed with Riemann, especially with his theory of abelian functions. When Riemann's work appeared, Weierstrass withdrew his paper from Crelle's Journal and did not publish it. They had a good understanding when Riemann visited him in Berlin in Here we begin directly with the so- called "abstract" manifolds. To illustrate our point of view, a series of examples is developed each time a new definition or theorem occurs. Thus, the reader will meet a detailed recurrent study of spheres, tori, real and complex projective spaces, and compact Lie groups equipped with bi-invariant metrics. Notice that all these examples, although very common, are not so easy to realize except the first as Riemannian submanifolds of Euclidean spaces. Borzellino, Mathematical Reviews, Classical results … are treated in detail. For this third edition, some topics … have been added and worked out in the same spirit. The book is almost self-contained, assuming in general only basic calculus. It contains nontrivial exercises with full solutions at the end. Properties are always illustrated by many detailed examples. The book continues to be an excellent choice for an introduction to the central ideas of Riemannian geometry.
