Finite field-dependent symmetries in perturbative quantum gravity
Sudhaker Upadhyay
In this paper we discuss the absolutely anticommuting nilpotent symmetries for perturbative quantum gravity in general curved spacetime in linear and non-linear gauges. Further, we…
New Hamiltonian analysis of Regge Teitelboim minisuperspace cosmology
Rabin Banerjee, Pradip Mukherjee, Biswajit Paul
A new Hamiltonian formulation of the minisuperspace cosmology following from the geodetic brane gravity model introduced by Regge and Teitelboim is presented. The model is consider…
Exact results in two dimensional chiral hydrodynamics with gravitational anomalies
Rabin Banerjee
An exact formulation of two dimensional chiral hydrodynamics with diffeomorphism and conformal anomalies is provided. The constitutive relation involving the stress tensor is compu…
Mass function and particle creation in Schwarzschild-de Sitter spacetime
Sourav Bhattacharya, Amitabha Lahiri
We construct a mass or energy function for the non-Nariai class Schwarzschild-de Sitter black hole spacetime in the region between the black hole and the cosmological event horizon…
