The issue of Branched Hamiltonian in F(T) Teleparallel Gravity
Manas Chakrabortty, Kaushik Sarkar, Abhik Kumar Sanyal
As in the case of Lanczos-Lovelock gravity, the main advantage of F(T) gravity is said to be that it leads to second order field equations, while F(R) gravity theory leads to fourt…

Validating variational principle for higher order theory of gravity
Soumendranath Ruz, Kaushik Sarkar, Nayem Sk +1
Metric variation of higher order theory of gravity requires to fix the Ricci scalar in addition to the metric tensor at the boundary. Fixing Ricci scalar at the boundary implies th…
