This exploration analyzes cosmological dynamics in modified gravity models, revealing stability features and energy behavior.
Key Points
The research aims to investigate the cosmological dynamics of a modified gravity model using dynamical systems to identify stable phases and transitions.
Constructed an autonomous system using two dimensionless variables.
Analyzed three critical points for stability and expansion behavior.
Conducted statefinder analysis to compare against standard cosmological models.
Identified critical points corresponding to different cosmic phases: matter-dominated, stable de-Sitter, and transitional phases.
Confirmed a stable late-time accelerating attractor in the modified gravity framework.
Showed that the effective equation of state lies in the quintessence region, supporting accelerated expansion.
