摘要 In this study,we investigate the expansion of the FRLW universe in the open,closed,and flat geometries.The universe is dominated by a scalar field(spatially homogeneous)as a source of dark energy.We consider the three different classes of scalar fields-quintessence,tachyonic,and phantom field-for our analysis.A mathematical analysis is carried out by considering these three scalar fields with exponential and power-law potentials.Both potentials give exponential expansion in the open,closed,and flat FRLW universes.It is found that quintessence,tachyonic,and phantom scalar fields are indistinguishable under the slow roll approximation.
