The Qualitative and Numerical Analysis of the Cosmological Model Based on Phantom Scalar Field with Self (1610.04443v1)

Abstract: In this paper we investigate the asymptotic behavior of the cosmological model based on phantom scalar field on the ground of qualitative analysis of the system of the cosmological model's differential equations and show that as opposed to models with classical scalar field, such models have stable asymptotic solutions with constant value of the potential both in infinite past and infinite future. We also develop numerical models of the cosmological evolution models with phantom scalar field in this paper. {\bf keywords}: cosmological model, phantom scalar field, quality analysis, asymptotic behavior, numerical simulation, numerical gravitation.\ {\bf PACS}: 04.20.Cv, 98.80.Cq, 96.50.S 52.27.Ny
