-Term and Cosmological Constant from CJD Action
Prasanta Mahato
In the gravity without metric formalism of Capovilla, Jacobson and Dell, the topological -term appears through a canonical transformation.The origin of this canonical transforma…
Gravitational Constant and Torsion
Prasanta Mahato
Riemann-Cartan space time is considered here. It has been shown that when we link topological Nieh-Yan density with the gravitational constant then we get Einstein-Hilbert…
Torsion, Dirac Field, Dark Matter and Dark Radiation
Prasanta Mahato
The role of torsion and a scalar field in gravitation, especially, in the presence of a Dirac field in the background of a particular class of the Riemann-Cartan geometry is co…
Torsion, Scalar Field, Mass and FRW Cosmology
Prasanta Mahato
In the Einstein-Cartan space , an axial vector torsion together with a scalar field connected to a local scale factor have been considered. By combining two particular terms f…
de Sitter group and Einstein-Hilbert Lagrangian
Prasanta Mahato
Axial vector torsion in the Einstein-Cartan space is considered here. By picking a particular term from the SO(4,1) Pontryagin density and then modifying it in a SO(3,1) in…
