摘要

我们采用动力学系统方法研究了 FHDE 在 f(T)f(T) 引力下的宇宙动力学。通过引入合适的无量纱变量,场方程被转化为封闭系统,从而实现系统的相空间分析。 resulting system admits four critical points, including two saddle points corresponding to radiation and matter-dominated epochs, and two stable points associated with a DE-dominated phase and a de Sitter solution. The radiation- and matter-dominated critical points are found to possess a saddle character in phase space, ensuring their transient nature and enabling the cosmological evolution to naturally progress toward a stable late-time accelerated attractor. The stable critical points describe accelerated expansion with effective equations of state compatible with DE and de Sitter regimes. Overall, the analysis indicates that f(T)f(T) gravity is capable of reproducing the standard cosmological sequence within a consistent dynamical framework.
