论文摘要
我们研究了混合公制理论中Liouville综合宇宙学模型的存在。具体而言,我们将对称条件用于在野外方程的动量保护定律中存在二次的情况,作为确定理论未知功能形式的约束条件。在本研究中发现的集成系统的确切和分析解决方案是根据四边形和洛朗扩展的。
We investigate the existence of Liouville integrable cosmological models in hybrid metric-Palatini theory. Specifically we use the symmetry conditions for the existence of quadratic in the momentum conservation laws for the field equations as constraint conditions for the determination of the unknown functional form of the theory. The exact and analytic solutions of the integrable systems which found in this study are presented in terms of quadratics and Laurent expansions.
