论文摘要
研究了以后的F（r，g）修饰的重力的两个不同的弹跳方案的稳定性，即双曲线余弦弹跳模型和物质主导的弹跳模型。在描述了F（R，G）修饰的重力的主要特征之后，重建了来自该理论的两个不同的弹跳场景，并讨论了它们在晚期的稳定性。证明双曲线余弦模型的稳定性，而这里选择的混凝土弹跳模型似乎并没有完成以后稳定的必要条件。
The stability of two different bounce scenarios from F(R,G) modified gravity at later times is studied, namely a hyperbolic cosine bounce model and a matter-dominated one. After describing the main characteristics of F(R,G) modified gravity, the two different bounce scenarios stemming from this theory are reconstructed and their stability at late stages is discussed. The stability of the hyperbolic cosine model is proven, while the concrete matter-bounce model here chosen does not seem to accomplish the necessary conditions to be stable at later times.
