Keywords: SU(1,1) Lie algebra Inflation model of the universe Dark energy Vacuum energy Scalar field Probability density a b s t r a c t Quantum behavior of scalar fields and vacuum energy density in the inflationary universe are investigated using SU(1,1) Lie algebraic approach. Wave functions describing the evolution of scalar fields that have been thought to have driven cosmic inflation are identified in several possible quantum states at the early stage of the universe, such as the Fock
