Determine of cosmological parameters for the some Bianchi type models of the universe

In this study it is provided information about the cosmological model studies, the cosmological principles are discussed and the General Relativity Theory (GRT), Brans-Dicke theory and Bianchi classification are explicitly explained. After that, cosmological parameters are inspected within the framework of General Relativity theory for Friedmann Robertson Walker (FRW) space-time and Einstein field equations studies are carried out for obtaining the general solution. Then, primarily, cosmological parameters are identified within the framework of Brans -Dicke theory for FRW space-time and obtained new solutions of the field equations. Finally, cosmological parameters are determined within the framework of GRT for locally rotationary symmetric Bianchi type I space-time and found some new solutions of field equations.
