Conflict between some higher-order curvature invariant terms
Dalia Saha, Mohosin Alam, Ranajit Mandal +1
A viable quantum theory does not allow curvature invariant terms of different higher orders to be accommodated in the gravitational action. We show that there is indeed a conflict…
Early universe in view of a modified theory of gravity
Ranajit Mandal, Dalia Saha, Mohosin Alam +1
We study the quantum evolution of the early universe, its semi-classical analogue together with inflationary regime, in view of a generalized modified theory of gravity. The action…
Probing the early universe with a generalized action
Ranajit Mandal, Dalia Saha, Mohosin Alam +1
Possibly, the most general action in the background of isotropic and homogeneous space-time has been considered to study the quantum evolution of the early universe, apart from a c…
Cosmological Lorentzian Wormholes via Noether symmetry approach
Abhik Kumar Sanyal, Ranajit Mandal
Noether symmetry has been invoked to explore the forms of a couple of coupling parameters and the potential appearing in a general scalar-tensor theory of gravity in the background…
