conformal mappings from Ricci symmetric spaces onto Einstein spaces

in this paper we: defined Riemannian spaces, conformal mappings, Einstein spaces, Riemannian symmetric spaces, Ricci spaces and Ricci symmetric spaces, recall the fundamental properties of these spaces

conformal mapping between Einstein spaces

in this paper we: 1) defined Riemannian space , conformal mapping, Einstein space , Ricci recurrent Einstein space. 2) study conformal mapping between Einstein spaces corresponding flat surface, and Ricci recurrent Einstein space.
