Connections and Curvature,o the differentiable category. Our next endeavor is to try and understand how bundles fail to be products by parallel translating vectors around closed loops. This depends of course on what is meant by “parallel translation” (which is explained in the section below), but roughly speaking, if paralle

Metric Structures,anifold is called a . A . is a differentiable manifold together with a Riemannian metric. We will often write (u, v) instead of . and lul for (.)./.. Maps that preserve metric stuctures are of fundamental importance in Riemannian geometry: D. 1.1. Let (ξ., (, ).), i = 1, 2, be Euclidean bundles over

Homotopy Groups and Bundles Over Spheres,try and convince the reader that we are not introducing new objects when, for example, we consider the pullback . of a bundle via a continuous map .: Explicitly, we will show that any continuous map between manifolds is homotopic to a differentiable one, and the latter can be chosen to be arbitrarily close to the original one.

Metric Structures,Maps that preserve metric stuctures are of fundamental importance in Riemannian geometry: D. 1.1. Let (ξ., (, ).), i = 1, 2, be Euclidean bundles over .i. A map .ξ. is said to be . if (1) . maps each fiber ∏.(p.) linearly into a fiber ∏. (.), for p. ∈ M.; and (2) . . for u, v ∈ ∏.(p), . ∈ M..
