Abstract


The present paper studies the main type of conformal reducible conformally flat spaces.
We prove that these spaces are subprojective spaces of Kagan, while Riemann tensor is defined by a vector defining the conformal mapping.
This allows to carry out the complete classification of these spaces.
The obtained results can be effectively applied in further research in mechanics, geometry, and general theory of relativity.
Under certain conditions the obtained equations describe the state of an ideal fluid and represent quasi-Einstein spaces.
Research is carried out locally in tensor shape.
Keywords:
pseudo-Riemannian spaces; conformal reducible spaces; conformally flat spaces; subprojective spaces of Kagan.
