| dc.description.abstract | 
 The paper contains necessary conditions allowing to reduce matrix tensors of pseudo-Riemannian spaces to special forms called semi-reducible, under assumption that the tensor defining tensor characteristic of semireducibility spaces, is idempotent.
 The tensor characteristic is reduced to the spaces of constant curvature, Ricci-symmetric spaces and conformally flat pseudo-Riemannian spaces.
 
 The obtained results can be applied for construction of examples of spaces belonging to special types of pseudo-Riemannian spaces.
 
 The research is carried out locally in tensor shape, without limitations imposed on a sign of a metric.
