Testing Gravity with Logarithmic Equation of State Using Latest Cosmological Data
Chaymae Karam, Dalale Mhamdi, Taoufik Ouali +2
In this paper, we investigate the late-time accelerated expansion of the Universe in power law gravity, where a logarithmic dark energy parametrization is considered: $ω_{de…

Dynamics of Linear Scalar Perturbation in f(Q)+f(T) class of f(Q,T) gravity
Houda Filali, Rachid Ahl Laamara, Mohamed Bennai +1
In this work, we study the f(Q,T) model of symmetric teleparallel modified gravity in the framework of cosmological perturbation theory. Using a general approach, we extract the di…
