摘要：

The present cosmological model consists of two scalar fields which are minimally coupled to gravity and having a mixed kinetic term. In the background of homogeneous and isotropic FLRW space-time the present model is characterized by the coupling function and the potential function which are functions of one of the scalar fields. Using symmetries of the 3D augmented space, homothetic and killing vectors are determined. Finally, quantum cosmology has been formulated for the present model and the wave function of the universe has been evaluated.
