论文摘要
我们研究了巨大的重力和最小巨大的大狂热理论的未来宇宙学奇异性。在这方面，我们考虑了大型宇宙中可能有限的未来奇异性类别，例如突然的，大裂口，大冻结和大制动奇异性。在具有开放式扩展宇宙的DRGT模型中，我们将来会在有限的时间内获得突然的奇异性，通常不考虑任何特定现实状态的状态方程，是不可避免的，除了流体密度，除了所有动态的物理量，例如无限制的压力方法。为了完成我们的研究，我们在最小的巨大大狂热理论的背景下搜索了未来的宇宙学奇点，我们发现该理论的宇宙学遭受了突然和大制动奇点的影响，在这种情况下，我们可以看到模型的参数可以删除零突然的奇异性。
We study the future cosmological singularities in the framework of massive gravity and minimal massive bigravity theory. In this regards, we consider the possible classes of finite-time future singularities such as sudden, big rip, big freeze and big brake singularities in the massive universe. In dRGT model with an open expanding universe we obtain the sudden singularity in the future at a finite-time which generally without taking account of any particular realistic equation of state, is not avoidable and except the fluid density, all dynamical physical quantities such as pressure approach to infinity. To complete our study, we search the future cosmological singularities in the context of minimal massive bigravity theory and we find that the cosmology of this theory suffers from the sudden and big brake singularities, in which we can see that the parameters of the model approaches to zero the sudden singularity can be removed.
