In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form which vanishes under the Laplacian operator of the metric. Moreover the Thom class in cohomology is represented by a differential form having a nice Gaussian shape peaked along the zero section. We then investigate this Gaussian Thom form in greater detail. We show it is universally defined as an equivariant differential form on Euclidean space F3" for the action of SO(n).
But if one is comfortable with differential forms, then de Rham theory is a setting in which theorems such as Poincare duality can be proved with a minimum of pain. It is also very edifying to see the Poincare dual of a submanifold as a differential form. There is then a natural transition to Cech cohomology and double complexes. By using the de Rham theory of differential forms as a prototype of cohomology, the machineries of algebraic topology are made easier to assimilate. With its stress on concreteness, motivation, and readability, this book is equally suitable for self-study and as a one-semester course in topology.

In this chapter, the integral of an exterior differential form over a submanifold of a given manifold, whose dimension is equal to the degree of the exterior form, is treated as a linear operator assigning a real number to that form. As is well known, the form reduces to a simple form on such a submanifold and the.

With its stress on concreteness, motivation, and readability, this book is equally suitable for Cited by: The integration on forms concept is of fundamental importance in differential topology, geometry, and physics, and also yields one of the most important examples of cohomology, namely de Rham cohomology, which (roughly speaking) measures precisely the extent to which the fundamental theorem of calculus fails in higher dimensions and on general manifolds.
De Rham cohomology is the cohomology of differential forms. This book offers a self-contained exposition to this subject and to the theory of characteristic classes from the curvature point of view.
It requires no prior knowledge of the concepts of algebraic topology or cohomology. The first ten chapters study cohomology of open sets in Euclidean space, treat smooth manifolds and their. The guiding principle in this book is to use differential forms as an aid in exploring some of the less digestible aspects of algebraic topology.
Accord ingly, we move primarily in the realm of smooth manifolds and use the de Rham theory as a prototype of all of cohomology.

They also give you a start with algebraic topology in the sense that one can extract topological information about a manifold from its space of differential forms.

It is entirely devoted to the subject of differential forms and explores a lot of its important particular, our book provides a detailed and lucid account of a fundamental result in the theory of differential forms which is, as a rule, not touched upon in undergraduate texts: the isomorphism between the Čech cohomology groups.
An appendix gives a proof of the equivariant de Rham theorem, demonstrating that equivariant cohomology can be computed using equivariant differential forms. Examples and calculations illustrate new concepts.
Exercises include hints or solutions, making this book suitable for self-study. “Rational homotopy theory is today one of the major trends in algebraic topology. Despite the great progress made in only a few years, a textbook properly devoted to this subject still was lacking unt.
Differential forms are things that live on manifolds. So, to learn about differential forms, you should really also learn about manifolds. To this end, the best recommendation I can give is Loring Tu's An Introduction to develops the basic theory of manifolds and differential forms and closes with a exposition of de Rham cohomology, which allows one to extract topological.
This book is an introductory graduate-level textbook on the theory of smooth manifolds. Its goal is to familiarize students with the tools they will need in order to use manifolds in mathematical or scientific research smooth structures, tangent vectors and covectors, vector bundles, immersed and embedded submanifolds, tensors, differential forms, de Rham cohomology, vector fields, flows 5/5(6).

It was adopted as standard in commutative algebra and algebraic geometry somewhat later, once the need was felt to adapt methods from calculus and geometry over the complex numbers to contexts where such methods are.
For each n≥1, compute the de Rham cohomology groups of Open image in new window; and for each nonzero cohomology group, give specific differential forms whose cohomology classes form a basis.
Let M be a connected smooth manifold of dimension n ≥3. Book • 2nd Edition • Then we introduce the de Rham cohomology of a smooth manifold with boundary M, which measures in a precise way the difference between closed and exact differential forms on M.
Actually, we introduce the notion of a smooth pair Differential Forms, 2nd Edition.The theory of characteristic classes provides a meeting ground for the various disciplines of differential topology, differential and algebraic geometry, cohomology, and fiber bundle theory.
As such, it is a fundamental and an essential tool in the study of differentiable manifolds. In this volume, the authors provide a thorough introduction to characteristic classes, with detailed studies of 5/5(2). Yes, this is an excellent book, and will serve, even now, over forty-three years after its first appearance (kudos to Dover, as always, for reissuing the book), as an excellent introduction to not just sheaf cohomology (and ipso facto the category theory everyone needs to know) but also to differential geometry proper, the theory of fiber and.
