Observational Constraints on Late-Time Cosmological Expansion in Minimal R + Alpha R^2 Gravity

We investigate the numerical dynamics and observational viability of the minimal modified gravity model defined by f(R) = R + alpha R^2 in the late-time Universe. By recasting the higher-derivative gravitational dynamics into an autonomous coupled system of first-order differenti...
