Riemannian geometry is the branch of differential geometry that studies Riemannian manifolds, defined as smooth manifolds with a Riemannian metric (an inner product on the tangent space at each point that varies smoothly from point to point). This gives, in particular, local notions of angle, length of curves, surface area and volume.
Let X and Y be oriented smooth closed manifolds, and f: X → Y a continuous map. Let v f =f * (TY) − TX in the K-group K(X). If dim(X) ≡ dim(Y) mod 2, then (()) = (() / ^ ()),where ch is the Chern character, d(v f) an element of the integral cohomology group H 2 (Y, Z) satisfying d(v f) ≡ f * w 2 (TY)-w 2 (TX) mod 2, f K* the Gysin homomorphism for K-theory, and f H* the Gysin ...
Let M be a smooth manifold. A (smooth) singular k-simplex in M is defined as a smooth map from the standard simplex in R k to M. The group C k (M, Z) of singular k-chains on M is defined to be the free abelian group on the set of singular k-simplices in M. These groups, together with the boundary map, ∂, define a chain complex.
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 equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.

In mathematics, specifically in the field of differential topology, Morse homology is a homology theory defined for any smooth manifold.It is constructed using the smooth structure and an auxiliary metric on the manifold, but turns out to be topologically invariant, and is in fact isomorphic to singular homology.
The jet space can be endowed with a smooth structure (i.e. a structure as a C ∞ manifold) which make it into a topological space. This topology is used to define a topology on C ∞ ( M , N ). For a fixed integer k ≥ 0 consider an open subset U ⊂ J k ( M , N ), and denote by S k ( U ) the following:
