Abstract

We investigate the background dynamics of a class of models with noncanonical scalar field and matter both in FLRW closed and open spacetime. The detailed dynamical system analysis is carried out in the bouncing scenario. Cosmological solutions satisfying the stability and bouncing conditions are obtained using the tools of a dynamical system.
