摘要：
We study the geometry of the phase space of spatially flat Friedmann-Lemaitre Robertson-Walker models in f (R) gravity, for a general form of the function f ( R). The equilibrium points ( de Sitter spaces) and their stability are discussed, and a comparison is made with the phase space of the equivalent scalar-tensor theory. New effective Lagrangians and Hamiltonians are also presented.
