Overview

Analysis explores late-time expansion dynamics in modified gravity models, suggesting implications for cosmic evolution.

Key Points

  • This research aims to analyze the cosmological dynamics of a modified gravity theory and identify stable behavior.
  • Reformulated field equations into an autonomous system of ordinary differential equations.
  • Identified and examined the stability of eight critical points.
  • Analyzed the conditions for late-time accelerated expansion as a stable attractor.
  • Utilized diagnostics to characterize cosmic phases and compared findings with observational data.
  • Obtained stable attractors indicating possible late-time accelerated expansion.
  • Identified transition redshift and parameters consistent with observational bounds.
  • Demonstrated that the model effectively resembles the ΛCDM paradigm when analyzed with Hubble, BAO, and Pantheon data.
