Chaplygin-gas solutions of f(R) gravity
(World Scientific Publishing, 2016)We explore exact f(R) gravity solutions that mimic Chaplygin-gas inspired CDM cosmology. Starting with the original, generalized and modified Chaplygin gas equations of state, we reconstruct the forms of f(R) Lagrangians. ... -
On f(R) gravity in scalar-tensor theories
(World Scientific, 2017)We study f(R) gravity models in the language of scalar–tensor (ST) theories. The correspondence between f(R) gravity and ST theories is revisited since f(R) gravity is a subclass of Brans–Dicke models, with a vanishing ...
