We reconsider the recently proposed mimetic gravity, focusing in particular on whether the
theory is able to reproduce the inferred flat rotation curves of galaxies. We extend the theory …

We investigate classes of shear-free cosmological dust models with irrotational fluid flows
within the framework of f (T) gravity. In particular, we use the 1+ 3 1+ 3 covariant formalism …

The consideration of a 1+ 3 covariant approach to cold dark matter universe with no shear
cosmological dust model with irrotational flows is developed in the context of f (G) gravity …

We present a reconstruction technique for models of f (R) gravity from the Chaplygin scalar
field in flat de Sitter spacetimes. Exploiting the equivalence between f (R) gravity and scalar …

In this contribution, we consider the well-known equivalence between f (R) gravity and Brans–
Dicke-type scalar–tensor theories to study the evolution of scalar cosmological perturbations …

In this contribution, classes of shear-free cosmological dust models with irrotational fluid
flows will be investigated in the context of scalar-tensor theories of gravity. In particular, the …

We investigate classes of shear-free cosmological dust models with irrotational fluid flows
within the framework of $ f (T) $ gravity. In particular, we use the $1+ 3$ covariant formalism …
