Thawing F(R) cosmology
Mahmood Roshan, Fatimah Shojai
We consider Brans-Dicke (BD) scalar tensor theory in the conformally transformed Einstein frame. In this frame BD theory behaves like an interacting quintessence model. We find the…

Tracking cosmology
Mahmood Roshan, Fatimah Shojai
Metric gravity theories are conformally equivalent to models of quintessence in which matter is coupled to dark energy. We derive a condition for stable tracker solution for…

Cosmological solutions of time varying speed of light theories
Mahmood Roshan, Maryam Nouri, Fatimah Shojai
We consider scalar-tensor theory for describing varying speed of light in a spatially flat FRW space-time. We find some exact solutions in the metric and Palatini formalisms. Also…
