Abstract
We propose a unified description of inflation, dark energy, and dark matter within a two-scalar-field cosmological model. One of the scalar fields plays the role of the inflaton and, afterward, of dark matter; the second field plays the role of dark energy. For certain values of the parameters of the model, the cosmological solutions arising in this model reproduce the main features of the evolution of the Universe.
