Exact solutions of the FLRW cosmological model via invariants of the Hamilton-Jacobi method
E. Ahmadi-Azar, K. Atazadeh, A. Eghbali
In this study, we proceed to solve the field equations of the spatially flat Friedman-Lemaitre-Robertson-Walker (FLRW) cosmological model in the presence of the cosmological consta…

Linear independence of field equations in the Brans-Dicke theory
E. Ahmadi-Azar, K. Atazadeh, A. Eghbali
In solving the Brans-Dicke (BD) equations in the BD theory of gravity, their linear independence is important. This is due to fact that in solving these equations in cosmology, if…
