If this is the first time you use this feature, you will be asked to authorise Cambridge Core to connect with your account. The definition of an isometry requires the notion of a metric on the manifold; a manifold with a (positive-definite) metric is a Riemannian manifold, one with an indefinite metric is a pseudo-Riemannian manifold. Riemannian and pseudo-Riemannian geometry - metrics, - connection theory (Levi-Cevita), - geodesics and complete spaces - curvature theory (Riemann-Christoffel tensor, sectional curvature, Ricci-curvature, scalar curvature), - tensors - Jacobi vector fields. In pseudo-Riemannian geometry we deal with spaces (pseudo-Riemannian manifolds), which take pseudospheres as scales at local coordinates (more precisely, at infinitesimal level for each point).

If the dimension of M is zero, then M is a countable set equipped with the discrete topology (every subset of M is an open set). This pseudo-Riemannian generalisation of the prescribed scalar curvature problem is the topic of the present thesis. For example, the Ricci scalar, and the Kretschmann scalar, RµναβR µναβ, are simple examples of such invariants [1]. Vector calculus can be defined on other 3-dimensional real vector spaces if they have an inner product or more generally a symmetric nondegenerate form and djvergence orientation; note that this is less data than an isomorphism to Euclidean space, as it does not require a set of coordinates a frame of referencewhich reflects the fact that.

If dimM = 1, then M is locally homeomorphic to an open interval; if dimM = 2, then it is locally homeomorphic to an open disk, etc. The analogous conditions on the other two components characterize metrics having constant scalar curvature and, respectively, parallel Ricci tensor, including the Einstein metrics. Riemannian geometry is the branch of differential geometry that studies Riemannian manifolds, smooth manifolds with a Riemannian metric, i. Introduction. For a fixed n ∈ N, the curvature tensor of a pseudo-Riemannian metric, as well as its covariant derivatives, satisfy certain identities that hold on any manifold of dimension less or equal than n.
