Characteristic Classes,Let = ∏∏ : . → M denote a rank n bundle over . with connection V and curvature . The Bianchi identity . = 0 from Exercise 94 implies that certain polynomial functions in . are closed differential forms on . and thus represent cohomology classes in .(M, ℝ). These classes are called . of ξ, and turn out to be independent of the choice of connection.

Fiber Bundles, In this case, each point of . has a neighborhood diffeomorphic to a product . x ℝ., where . is an open set in M. Of course, . itself need not be diffeomorphic to . x R . In most of the sequel, we will be concerned with manifolds that, roughly speaking, look locally like products. As usual, all maps are assumed to be differentiable.
