On a class of curvature preserving almost geodesic mappings of manifolds with affine connection

Abstract

In this paper we pay attention to a particular case of almost geodesic mappings of the first type between (differentiable) manifolds with affine connection. We use here lassical tensor methods and the apparatus of partial differential equations. We prove that under the mappings under consideration, the invariant geometric object is just the (Riemannian) curvature tensor of the connection. We present the basic equations of the lass of mappings under consideration in an equivalent form of the Cauchy system in covariant derivatives.
