    Phase plane of a non-canonical scalar field model and cosmological consequences
    (University of North Bengal, 2025-03) Bhattacharya, Agnidipto; Biswas, Sujay Kr.
    This work deals with an investigation of phase plane analysis for a non-canonical scalar field in the background dynamics of spatially flat, homogeneous and isotropic Friedmann-Robertson-Walker (FRW) universe. Here, gravity is nonminimally coupled to scalar field having a real scalar field potential explicitly depending on cosmic time ‘t’. Nonlinear field equations are reduced to an autonomous system of ordinary differential equations by the suitable choice of dynamical variables. From the analysis of critical points, we have found the future decelerating phase of evolution of the universe.
