Review of Tensors, Manifolds, and Vector Bundles,reviewing the basic definitions and properties of tensors on a finite-dimensional vector space. When we put together spaces of tensors on a manifold, we obtain a particularly useful type of geometric structure called a “vector bundle,” which plays an important role in many of our investigations.

Curvature,ocally isometric, we are led to a definition of the Riemannian curvature tensor as a measure of the failure of second covariant derivatives to commute. Then we prove the main result of this chapter: A manifold has zero curvature if and only if it is flat, that is, locally isometric to Euclidean spac

Curvature and Topology, and topology. Before treating the topological theorems themselves, we prove some comparison theorems for manifolds whose curvature is bounded above. These comparisons are based on a simple ODE comparison theorem due to Sturm, and show that if the curvature is bounded above by a constant, then the m
