Cosmological solutions and growth index of matter perturbations in f(Q) gravity

The present work studies one of Einstein’s alternative formulations based on the non-metricity scalar Q generalized as f ( Q ) theory. More specifically, we consider the power-law form of f ( Q ) gravity i.e. f ( Q ) = Q + α Q n . Here, we analyze the behavior of the cosmological model at the backgro... View More
