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…

Cosmological solutions in the Brans-Dicke theory via invariants of symmetry groups
E. Ahmadi-Azar, K. Atazadeh, A. Eghbali
We proceed to obtain an exact analytical solution of the Brans-Dicke (BD) equations for the spatially flat () Friedmann-Lamaitre-Robertson-Walker (FLRW) cosmological model in…
