Perfect fluid solutions of Brans-Dicke and f (R) cosmology
Çiftçi, Dilek K.; Faraoni, Valerio (Academic Press Inc Elsevier Science, 2018)Brans-Dicke cosmology with an (inverse) power-law potential is revisited in the light of modern quintessence and inflation models. A simple ansatz relating scale factor and scalar field recovers most of the known solutions ... -
Symmetry of Brans-Dicke gravity as a novel solution-generating technique
Faraoni, Valerio; Çiftçi, Dilek K.; Belknap-Keet, Shawn D. (Amer Physical Soc, 2018)A symmetry of Brans-Dicke gravity in (electro) vacuo or in the presence of conformally invariant matter is presented and used as a solution-generating technique starting from a known solution as a seed. This novel technique ...
