摘要：

We show that the quasi-exponential solution exp (Bt - At2) of R + alphaR2 gravity is an attractor for all homogeneous and isotropic solutions of higher order gravity theories derived from a lagrangian that is an arbitrary analytic function of the scalar curvature R. This indicates that a generalized form of the cosmic no-hair conjecture is valid in the framework of higher order gravity theories.
