Reconstruction of f(T) and f(R) gravity according to (m,n)-type holographic dark energy    [PDF]

M. Umar Farooq, Mubasher Jamil, Davood Momeni, Ratbay Myrzakulov
Motivated by earlier works on reconstruction of modified gravity models with dark energy components, we extend them by considering a newly proposed model of (m, n)- type of holographic dark energy for two models of modified gravity, f(R) and f(T) theories, where R and T represent Ricci scalar and torsion scalar respectively. Specifically we reconstruct the two later gravity models and discuss their viability and cosmography. The obtained gravity models are ghost free, compatible with local solar system tests and describe effective positive gravitational constant.
