Late-time cosmology and structure formation in quadratic f(Q) gravity
We study the cosmological dynamics of the quadratic symmetric teleparallel gravity model f(Q)=Q+αQ2+β, which introduces an H4 correction to the Friedmann equation due to Q∝H2. Using the exact algebraic solution for H(z), we reconstruct the effective dark-energy sector and compare the background evol...
