| Abstract: | The evolution of a homogeneous multicomponent cosmological model with interacting spinor, vector, and scalar fields in the
presence of dark energy described by the ideal liquid with the corresponding state equation is considered. The source of the
vector and spinor fields is the kinetic energy of the inflation (scalar) field that is modeled by introduction of Lagrangians
for the spinor and vector fields interacting with the scalar field through the squared gradient. A system of the dynamic Einstein–Proca–Klein–Fock
and ideal liquid equations in the presence of interaction of the cosmological model components is solved. The role of individual
components in the process of model evolution is elucidated. |
