Possible fluid interpretation and tidal force equation on a generic null hypersurface in Einstein-Cartan theory
Sumit Dey, Bibhas Ranjan Majhi
The dynamical evolution of the Hajicek -form is derived in Einstein-Cartan (EC) theory. We find that like Einstein theory of gravity, the evolution equation is related to a proj…

Kinematics and dynamics of null hypersurfaces in the Einstein-Cartan spacetime and related thermodynamic interpretation
Sumit Dey, Bibhas Ranjan Majhi
A general geometric construction of a generic null hypersurface in presence of torsion in the spacetime (Riemann-Cartan background), generated by a null vector , is being deve…
