Brans-Dicke-Maxwell solutions for higher dimensional static cylindrical symmetric spacetime
Çiftçi, Dilek K.; Delice, Özgür (Amer Inst Physics, 2015)In this paper, Brans-Dicke-Maxwell type vacuum solutions are considered for a static cylindrically symmetric spacetime in arbitrary dimensions. Exact solutions are obtained by directly solving the field equations for the ... -
Conformal cosmological black holes: Towards restoring determinism to Einstein theory
Hammad, Faycal; Çiftçi, Dilek K.; Faraoni, Valerio (Springer Heidelberg, 2019)A widespread solution-generating technique of general relativity consists of conformally transforming known seed solutions. It is shown that these new solutions always solve the field equations of a pathological Brans-Dicke ... -
Cylindrically symmetric vacuum solutions in higher dimensional Brans-Dicke theory
Baykal, Ahmet; Çiftçi, Dilek K.; Delice, Özgür (Amer Inst Physics, 2010)Higher dimensional, static, cylindrically symmetric vacuum solutions with and without a cosmological constant in the Brans-Dicke theory are presented. We show that for a negative cosmological constant and for specific ... -
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 ...
