Analyzing Conserved Currents in F(R) theory of gravity
Nayem Sk, Manas Chakrabortty, Abhik Kumar Sanyal
F(R) theory of gravity is claimed to admit a host of conserved currents under the imposition of Noether symmetry following various techniques. However, for a constrained system suc…

Some aspects of modified theory of gravity in Palatini formalism unveiled
Manas Chakrabortty, Nayem Sk, Abhik Kumar Sanyal
Under conformal transformation, f(R) theory of gravity in Palatini formalism leads to a Brans-Dicke type of scalar-tensor equivalent theory with a wrong sign in the effective kinet…
