Varying Gravitational Constant as Well as Cosmology from the Early Inflation to Late Acceleration and Future Universe

S. K. Srivastava

Here, cosmology is obtained from the variable gravitational constant $G \propto ϕ^{- 2}$ with $ϕ (x)$ being a scalar and its fluctuations around the ground state. The gravitationa…

$f (R)$ -Cosmolgy from Early Universe Upto Future Cosmic Collapse and its Avoidance

S. K. Srivastava

In the present model, a unified picture of cosmology from early inflation to late acceleration is obtained from $f (R) -$ gravity with non-linear terms $R^{2}$ and $R^{5}$ of scalar…
