Cosmological dynamics of a nonminimally coupled scalar field system and its late time cosmic relevance
We investigate the cosmological dynamics of a nonminimally coupled scalar field system described by $F(\ensuremath{\phi})R$ coupling with $F(\ensuremath{\phi})=(1\ensuremath{-}\ensuremath{\xi}{\ensuremath{\phi}}^{N})R(N\ensuremath{\ge}2)$ and the field potential $V(\ensuremath{\phi})={V}_{0}{\ensuremath{\phi}}^{n}$. We use a generic set of dynamical variables to bring out new asymptotic regimes of the underlying dynamics. However, our dynamical variables miss the most important fixed …
