Growth of perturbations in higher dimensional Gauss-Bonnet FRW cosmology
Ahmad Sheykhi, Bita Farsi
We explore the influences of the higher order Gauss Bonnet (GB) correction terms on the growth of perturbations at the early stage of a (n + 1)-dimensional Friedmann-Robertson-Walk…

Growth of Perturbations in Tsallis and Barrow Cosmology
Bita Farsi, Ahmad Sheykhi
We disclose the effects of the entropic corrections to the Friedmann equations on the growth of perturbations in the early stages of the universe. We consider two types of correcti…

Structure formation in mimetic gravity
Bita Farsi, Ahmad Sheykhi
We disclose the effects of an extra longitudinal degree of freedom on the evolution of perturbations in the framework of mimetic gravity. We consider a flat Friedmann-Robertson-Wal…
