dc.description.abstract In the present work we analyze the g-essence model for the particular Lagrangian: L = R + 2[αXn + ǫY − V (ψ, ¯ ψ)]. The g-essence models were proposed recently as an alternative and as a generalization to the scalar k-essence. We have presented the 3 types solutions of the g-essence model. We reconstructed the corresponding potentials and the dynamics of the scalar and fermionic fields according the evolution of the scale factor. The obtained results shows that the g-essence model can describes the decelerated and accelerated expansion phases of the univers ru_RU
