Specific Forms for the Action > s.a. Gauss-Bonnet Gravity;
  inflationary models [Starobinski model]; lovelock gravity.
  * Cosmic no hair theorem:
    Within 4th-order gravity with L = R + R2,
    the inflationary phase turns out to be a transient attractor.
  * \(R^{-1}\) theories:
    They lead to cosmological acceleration, which is part of their motivation;
    A 1/R term by itself is ruled out by constraints on scalar-tensor
    gravity, but could work as an extra contribution to the action.
