摘要
By adding a three-dimensional manifold to an eleven-dimensional manifold in supergravity, we obtain the action of F(R)-gravity and find that it is anomaly-free. We calculate the scale factor of the inflationary universe in this model and observe that it is related to the slow-roll parameters. The tensor-scalar ratio (Rtensor-scalar) is in good agreement with experimental data.
