Extensions of f(R) gravity : curvature-matter couplings and hybrid metric-Palatini gravity /
Recent cosmological observations have posed a challenge for traditional theories of gravity: what is the force driving the accelerated expansion of the universe? What if dark energy or dark matter do not exist and what we observe is a modification of the gravitational interaction that dominates the...
