AI总结:

本文提出利用引力理论的格点正规化研究大爆炸问题,证明了4D引力格点理论中空间折叠为零的高温相与长波极限下符合宇宙膨胀规律的低温相的存在。

摘要:

引力理论的格点正规化为研究大爆炸问题提供了新可能。在4D引力格点理论中,证明了高温相的存在,其特征是空间折叠成一个点且能量-动量张量归零。还展示了长波极限下低温相的存在,其几何性质和动力学符合已知概念:宇宙的膨胀首先遵循指数规律,然后平滑过渡到幂律状态。

英文摘要:

Lattice regularization of the theory of gravity provides a new possibility for study of the Big Bang problem. In the 4D lattice theories of gravity, the existence of a high-temperature phase is proved, which is characterized by the folding of space into a point and zeroing of the energy-momentum tensor. The existence of a low-temperature phase in the long-wave limit is also shown, the geometric properties of which and its dynamics correspond to known concepts: the expansion of the Universe first follows an exponential law, and then smoothly transitions to a power-law regime.
