We discuss a model of gravity with conformal symmetry appearing in the simplest extension of General Relativity with the Poincaré algebra terms. The nonlinear realization of symmetry causes the existence of five scalar fields. Therefore it looks desirable to use them for driving the inflation at the earliest stages of the Universe evolution. It is shown that the evolution of the scale factor depends on the number of fields included in the Lagrangian, but there are no inflationary solutions in this model. To drive inflation a more complicated model induced by extension of the Poincare algebra is required. [ABSTRACT FROM AUTHOR] |
