Dynamical system analysis and observational constraints of cosmological models in mimetic gravity
We study the dynamics of homogeneous and isotropic Friedmann-Lema\^itre-Robertson-Walker cosmological models with positive spatial curvature within the context of mimetic gravity theory by employing dynamical system techniques. Our analysis yields phase-space trajectories that describe physically re...

| description | We study the dynamics of homogeneous and isotropic
Friedmann-Lema\^itre-Robertson-Walker cosmological models with positive spatial
curvature within the context of mimetic gravity theory by employing dynamical
system techniques. Our analysis yields phase-space trajectories that describe
physically relevant solutions, capturing various stages of cosmic evolution. We
also employ Bayesian statistical analysis to constrain the cosmological
parameters of the models, utilizing data from Type Ia supernovae and Hubble
parameter data sets. The observational data sets provide support for the
viability of mimetic gravity models, which can effectively describe the
late-time accelerated expansion of the universe. |
