| Abstract | Lie group formalism is applied to Einstein field equations for perfect fluid distribution and pure radiation fields in the investigation of symmetries and exact solutions. The similarity reductions are obtained by determining the complete sets of point symmetries of these equations. The reduced ordinary differential equations are further studied and some non-trivial exact solutions are successfully furnished. |
