Inflation with F(T) Teleparallel Gravity
Manas Chakrabortty, Nayem Sk, Susmita Sanyal +1
We study early universe with a particular form of F(T) Telleparallel gravity theory, in which inflation is driven by a scalar field. To ensure slow rollover, two different potentia…
Revisiting conserved currents in F(R) theory of gravity via Noether symmetry
Nayem Sk., Abhik Kumar Sanyal
Noether symmetry of F(R) theory of gravity in vacuum and in the presence of pressureless dust yields F(R) \propto R^{3/2} along with the conserved current \frac{d}{dt}(a\sqrt R) in…
Revisiting Noether gauge symmetry for F(R) theory of gravity
Nayem Sk., Abhik Kumar Sanyal
Noether gauge symmetry for F(R) theory of gravity has been explored recently. The fallacy is that, even after setting gauge to vanish, the form of F(R) \propto R^n (where n \neq 1,…
Revisiting Noether symmetry approach in F(R)-tachyon Model
Nayem Sk., Abhik Kumar Sanyal
Recently, some authors have made a falsifiable claim that Noether gauge symmetry for F(R) theory of gravity coupled to a tachyon field enforces gauge to vanish and leads to F(R) \p…
Viability of Noether symmetry of F(R) theory of gravity
Kaushik Sarkar, Nayem Sk., Subhra Debnath +1
Canonization of F(R) theory of gravity to explore Noether symmetry is performed treating R - 6(\frac{\ddot a}{a} + \frac{\dot a^2}{a^2} + \frac{k}{a^2}) = 0 as a constraint of the…
Why Noether symmetry of F(R) theory yields three-half power law?
Kaushik Sarkar, Nayem Sk., Soumendranath Ruz +2
Noether symmetry of F(R) theory of gravity in vacuum or in matter dominated era yields three-half power law of R. We show that this particular curvature invariant term is very spec…
