论文摘要
通过Kantowski-Sachs背景空间确定了Einstein-Aether标量场理论中的精确和分析溶液。点对称的理论用于确定定义重力模型的未知函数的功能形式。保护定律用于降低场方程的顺序并编写分析解决方案。此外，为了了解宇宙学模型的身体行为，对重力场方程的渐近行为进行了详细分析。
Exact and analytic solutions in Einstein-Aether scalar field theory with Kantowski-Sachs background space are determined. The theory of point symmetries is applied to determine the functional form of the unknown functions which defines the gravitational model. Conservation laws are applied to reduce the order of the field equations and write the analytic solution. Moreover, in order to understand the physical behaviour of the cosmological model a detailed analysis of the asymptotic behaviour for the gravitational field equations is performed.
