On Preservation of the Riemann Tensor With Respect to Some Mappings of Affinely Connected Space // Russian Mathematics, 2018, Vol. 62, No. 9, pp. 1–6.1066-369X; 1934-810Xhttp://lib.udau.edu.ua/handle/123456789/6662This paper is devoted to geodesic and almost geodesic mappings of affinely connected spaces. We find conditions which ensure that the Riemann tensor is an invariant geometric object with respect to the studied mappings. In this work we present an example of a non-trivial geodesic mapping between the flat spaces.enRiemann tensorgeodesic mappingalmost geodesic mappingСтаття
