Towards (3+1) gravity through Drinfel'd doubles with cosmological constant

open access: yesPhysics Letters B, 2015
We present the generalisation to (3+1) dimensions of a quantum deformation of the (2+1) (Anti)-de Sitter and Poincaré Lie algebras that is compatible with the conditions imposed by the Chern–Simons formulation of (2+1) gravity.

Reparametrization invariant action for Gravity with Dynamical Determinant of Metric [PDF]

open access: yesarXiv
We present manifestly reparametrization invariant action for theory of gravity with dynamical determinant of metric. We show that it is similar to a reparametrization invariant action for unimodular gravity. We determine canonical form of the action and study structure of constraints.

Symmetry analysis in multi scalar-torsion cosmological model with quantum description

open access: yesEuropean Physical Journal C: Particles and Fields
A detailed symmetry analysis has been done for the present multi scalar-torsion gravity theory in the background of flat Friedmann Lema $$\hat{\text{ i }}$$ i ^ tre Robertson Walker (FLRW) space-time.
