Dynamics of f(R)-cosmologies containing Einstein static models
Naureen Goheer, Rituparno Goswami, Peter K. S. Dunsby
We study the dynamics of homogeneous isotropic FRW cosmologies with positive spatial curvature in -gravity, paying special attention to the existence of Einstein static model…
Gravitational collapse of a minimally coupled massless scalar field
Swastik Bhattacharya, Rituparno Goswami, Pankaj S. Joshi
We study here the evolution of a massless scalar field in a spacetime, developing from a regular initial spacelike surface. The Einstein equations and regularity and boundary condi…
The Existence of Einstein Static Universes and their Stability in Fourth order Theories of Gravity
Rituparno Goswami, Naureen Goheer, Peter K. S. Dunsby
We investigate whether or not an Einstein Static universe is a solution to the cosmological equations in gravity. It is found that only one class of theories admits a…
