Different types of torsion and their effect on the dynamics of fields
Subhasish Chakrabarty, Amitabha Lahiri
One of the formalisms that introduces torsion conveniently in gravity is the vierbein-Einstein-Palatini (VEP) formalism. The independent variables are the vierbein (tetrads) and th…

Conformal scalar and torsion do not go together
Subhasish Chakrabarty, Amitabha Lahiri
We investigate the conformal transformation of vierbein-Einstein-Palatini (VEP) action in terms of tetrads and spin connection . The transformation of the spin co…

Weak field limit in vierbein-Einstein-Palatini formalism and Fierz-Pauli Equation
Subhasish Chakrabarty, Amitabha Lahiri
We consider the weak field limit of gravity in the vierbein-Einstein-Palatini formalism, find the action and the equations for perturbations around an arbitrary background, and com…
