Abstract
We calculate the dynamical polarization function and solve a self-consistent gap equation in the random phase approximation in undoped ABC-stacked n-layer graphene. We find that the gap is maximal in trilayer graphene and decreases monotonously for because the effects of screening in the gap equation win over those connected with the flattening of electron bands as n increases.
