Einstein type curvature tensors and Einstein type tensors of generalized Riemannian space in the Eisenhart sense
By using decomposition of curvature tensors of generalized Riemannian space in the Eisenhart sense, the Einstein type curvature tensors and Einstein type tensors of that space are determined and defined. All these tensors ... -
Geodesic infinitesimal deformations of generalized Riemannian space
(Birkhaeuser Verlag AG, 2022-05-11)Infinitesimal deformations of subspaces of a generalized Riemannian space are studied in this paper. Variations of some geometric objects are found. Necessary and sufficient conditions which provide the existence of a ...
