论文摘要
Kasner宇宙学是一种真空和各向异性的范围，在一般相对性的环境下。在这项工作中，在另一种情况下，研究了这种宇宙学模型，即大黄蜂模型，其中洛伦兹对称性自发破裂。通过使用大黄蜂上下文，可以证明卡斯纳宇宙学的各向异性特征是合理的。因此，在宇宙学模型中，各向异性的起源可能是在洛伦兹对称性的破裂中。最后，提出了通货膨胀前宇宙学的应用。
Kasner cosmology is a vacuum and anisotropically expanding spacetime in the general relativity context. In this work, such a cosmological model is studied in another context, the bumblebee model, where the Lorentz symmetry is spontaneously broken. By using the bumblebee context it is possible to justify the anisotropic feature of the Kasner cosmology. Thus, the origin of the anisotropy in this cosmological model could be in the Lorentz symmetry breaking. Lastly, an application in the pre-inflationary cosmology is suggested.
