通过在超重力条件下将一个三维流形加到一个11维流形上,我们得到了ofF(R) -重力作用,并发现它是无异常的。我们计算了该模型中暴胀宇宙的尺度因子,并观察到它与慢滚参数有关。张量-标量比(Rtensor - scalar)与实验数据吻合较好。
By adding a three‐dimensional manifold to an eleven‐dimensional manifold in supergravity, we obtain the action ofF(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.
