ACM40090 Riemannian Differential Geometry

Academic Year 2022/2023

This module introduces the concepts, due initially to Riemann, of n-dimensional surfaces 'manifolds' that appear to be Euclidean locally in a neighbourhood of each point but globally may have curvature and a concept of distance - think of the 2-dimensional example of the surface of the Earth. The concepts of manifolds and their Differential Geometry, vector and tensor fields defined on them, appear throughout modern Applied and Computational Mathematics from fluids to dynamical systems to Einstein's theory of General Relativity.

Topics covered will include:

[Tensors over a vector space]: Dual vector space, the dual basis, multilinear maps, the tensor product, tensor spaces of type (r,s), operations on tensors.

[Manifolds]: Definition of a manifold, charts, diffeomorphism.

[Vectors on a manifold]: Parameterized curves, directional derivatives as vectors, derivations, forms.

[Maps on tensors]: The pul-back and push-forward, diffeomorphism as coordinate transformations. One parameter families of diffeomorphisms and the Lie derivative.

[Connections and curvature]: Definition of a connection, transformation of the coordinate components of a connection. The covariant derivative. Parallel transport, geodesics. The torsion and curvature tensors. The Bianchi identities.

[Riemannian manifolds]: The metric tensor, the Riemann tensor, geodesics as extremal curves, geodesic deviation.
