Modified theory of gravity and the history of cosmic evolution
B. Modak, Kaushik Sarkar, Abhik Kumar Sanyal
A continuous transition from early Friedmann-like radiation era through to late time cosmic acceleration passing through a long Friedmann-like matter dominated era followed by a se…
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…
