论文摘要
局部和全局相位空间描述和平均方法用于在标量场宇宙学的背景下，为FLRW和BIANCHI I指标找到解决方案的定性特征，具有任意的潜力和任意的耦合。平衡点在相位空间中的稳定性以及研究标量场差异的制度中的动力学。平衡点代表了宇宙学兴趣的某些解决方案，例如：几种类型的缩放溶液，一种代表僵硬流体的动力学主导的解决方案，一种由几何来源的有效能量密度主导的解决方案，一种典型的标量元素主导的溶液，真空de soltter de soltter与潜在的潜在解决方案相关的固定剂解决方案，是一种非构型溶液的最小值和无关紧要的物质统治性。所有这些都揭示了非常丰富的宇宙学现象学。
Local and global phase-space descriptions and averaging methods are used to find qualitative features of solutions for the FLRW and the Bianchi I metrics in the context of scalar field cosmologies with arbitrary potentials and arbitrary couplings to matter. The stability of the equilibrium points in a phase-space as well as the dynamics in the regime where the scalar field diverges are studied. Equilibrium points that represent some solutions of cosmological interest such as: several types of scaling solutions, a kinetic dominated solution representing a stiff fluid, a solution dominated by an effective energy density of geometric origin, a quintessence scalar field dominated solution, the vacuum de Sitter solution associated to the minimum of the potential, and a non-interacting matter dominated solution are obtained. All reveal a very rich cosmological phenomenology.
