The phase space of quintom cosmology

در یك جهان همگن و ایزوتروپیك، مدل كوئینتوم به عنوان یك سیستم دینامیكی معرف انرژی تاریك كه شامل میدان های فانتوم و كوئینت اسنس می باشد، ... The properties of quintom model are investigated in the isotropic and homogeneous universe as a dynamical system dominated by dark energy including the phantom and quintessence fields. A general discussion about the phase space of spatially non-flat universe is presented. We study the results for the later times without assuming the specific form of the potential. Then, we exhibit an obvious structure for the dynamics of the system.
