Abstract
The study of curvature operator properties, in particular, the one-dimensional curvature operator, is interesting for the understanding of the geometrical and topological structure of a homogeneous (pseudo)Riemannian manifold. In general case, this problem is quite difficult. Therefore, it is necessary to impose restrictions either on the class of manifolds or their dimension. An application of analytical calculation systems is possible if the dimension is finite. In this paper, mathematical and computer models for determining the components of the one-dimensional curvature operator and its spectrum (the set of eigenvalues) of non-reductive homogeneous (pseudo)R...
