    A symmetric space is called pseudo-Riemannian, if each symmetry, i.e. each S(p), is an isometry. The classification of all four dimensional pseudo-Riemannian symmetric spaces (with signature 1, - 3) reduces thus to two steps: Find all Lie triple systems in Minkowski space and find all covering spaces which give the same Lie triple universityofthephoenix.com by: 2. We provide examples of naturally reductive pseudo-Riemannian spaces, in particular an example of a naturally reductive pseudo-Riemannian 2-stepnilpotent Lie group (N,h,i N), such that h,i N is invariant under a left action and for which the center is degenerate.

    From now on, we restrict ourselves to the pseudo-Riemannian symmetric spaces G/H given in Sections 1 and 2. We keep to the notation used in Section 2 throughout the rest of this paper. Note that the Laplacian P on G/H is G- invariant. Concerning a geodesic . The space-time world of special relativity theory is the Lorentz space: the four-dimensional pseudo-Euclidean vector space of index 1, and that of the general relativity theory is a 4-dimensional pseudo-Riemannian manifold of index 1. Thus the Mathematica concepts contained in this notebook.

    Also, we give a number of examples of weakly symmetric pseudo-Riemannian manifolds, some mirroring the Riemannian case and some indicating the problems in extending Riemannian results to weakly symmetric pseudo-Riemannian spaces. In differential geometry, representation theory and harmonic analysis, a symmetric space is a pseudo-Riemannian manifold whose group of symmetries contains an inversion symmetry about every point. This can be made more precise, in either the language of Riemannian geometry or of Lie theory.

A pseudo-Riemannian manifold (,) is a differentiable manifold equipped with an everywhere non-degenerate, smooth, symmetric metric tensor. Such a metric is called a pseudo-Riemannian metric.

Applied to a vector field, the resulting scalar field value at any point of the manifold can be positive, negative or zero.
