Topological Static Spherically Symmetric vacuum Solutions in Gravity
Ratbay Myrzakulov, Lorenzo Sebastiani, Sergio Zerbini
The Lagrangian derivation of the Equations of Motion for topological static spherically symmetric metrics in -modified gravity is presented and the related soluti…
Topological electro-vacuum solutions in extended gravity
Guido Cognola, Emilio Elizalde, Lorenzo Sebastiani +1
Spherically symmetric static topological black hole solutions associated with some extended higher order gravitational models in the presence of a Maxwell-field are derived by mean…
Cosmic history of viable exponential gravity: Equation of state oscillations and growth index from inflation to dark energy era
Kazuharu Bamba, Antonio Lopez-Revelles, R. Myrzakulov +2
A generic feature of viable gravity is investigated: It is demonstrated that during the matter dominated era the large frequency oscillations of the effective dark energy ma…
