MAPPINGS OF PSEUDO-RIEMANNIAN SPACES WITH SEMI-SYMMETRIC AFFINOR STRUCTURE

Researches in Mathematics and Mechanics
The work consists of two parts. In the first part, using the deformation tensor of the connection, the general geometric properties of nontrivial mappings between two affine connection spaces without torsion are considered. A geometric object is constructed that represents the difference of the covariant derivatives of an arbitrary tensor with respect ...

On affine connections in a Riemannian manifold with a circulant metric and two circulant affinor structures

, 2010
In the present paper it is considered a class V of 3-dimensional Riemannian manifolds M with a metric g and two affinor tensors q and S. It is defined another metric \bar{g} in M. The local coordinates of all these tensors are circulant matrices. It is found: 1)\ a relation between curvature tensors R and \bar{R} of g and \bar{g}, respectively; 2)\ an ...
